Hello DigDugTrio72, I'm ThatOneMushroomGuy and I'll be the TA handling your critique today.

Arrows

Starting with your arrows your lines are looking fairly confident and smooth, which helps communicate a nice sense of fluidity in your arrows as they move through the world. You're keeping foreshortening in mind while constructing your arrows which allows you to make really good use of perspective and the depth of your page, this gives a nice extra layer of tridimensionality to your arrows.

Your usage of hatching helps you establish how your arrows twist and turn in space and further your own understanding of the tridimensional space these objects occupy, but do remember that your hatching lines must still follow the principles of ghosting and mark-making, they must have clear end and start points, be carefully planned and executed and not end at arbitrary points.

In general you're doing well, so keep tackling this exercise during your warm ups in order to take your understanding of arrows and 3D space further, experiment with the different ways arrows can twist and bend and move across space, try different rates of foreshortening and experiment with the negative space between overlaps, all of these will help you challenge yourself and develop your skills further.

Leaves

The linework for your leaves is looking smooth which helps communicate their fluidity and sense of energy, it's good that you're not only trying to capture how these structures sit statically within space, but also how they move across it from moment to moment.

However there are also some unnatural bends present in your leaf structures. Keep in mind that even though leaves are very flexible structures, that mostly applies to their length and not their width. They're like a piece of paper, not a piece of rubber, they can fold and bend in a lot of ways, but they can't stretch or compress, and if we try to force them to they'll simply rip apart.

Your addition of edge detail is generally looking good, as you don't usually attempt to capture more than one piece of edge detail at a time, and you generally keep the line thickness between your phases of construction roughly consistent, but don't forget to construct your edge detail additively as much as possible, that is, on top of your structure, avoid cutting back into the forms you've already drawn as that will cause us to focus too much on manipulating 2d shapes, rather than the 3d edges they represent.

Branches

Moving on to your branches they are coming along really decently made as you're generally following the instructions for the exercise, but they can still be improved. While it's good to see that you're drawing your edges in segments you're not starting your new segment back at the previous ellipse point and superimposing it on top of the preexisting mark, you're starting your new segments close to where your previous mark ended, which partially removes the healthy overlaps we seek to achieve in these structures.

So remember how branches should be approached, by having your segment start at the first ellipse point, extending it past the second ellipse and fully up to the halfway point to the third ellipse, afterwards you'll start a new segment, making sure to place your pen at the second ellipse and repeat this pattern until your entire branch is complete.

Don't forget to always draw through your ellipses twice as this will create a smoother and more confident look in your marks. When it comes to your application of the ellipse degree shift to your branches it can be improved, as it stands your degrees are too consistent and hardly change which is a mistake that flattens your structures. Remember that as a form shifts in relation to the viewer, so will the degree of the ellipses within that structure also shift.

Plant Construction Section

And now let's take a look at your plant constructions, which are generally coming along well made, as you're following the construction methods and techniques introduced in the lesson which allows you to construct really solid looking and believably tridimensional structures. I can see a good developing sense of spatial reasoning in these pages.

However there are some issues present in these pages which are holding you back from your full potential. So here are the points you should keep in mind whenever you tackle these exercises again so that you can continue to develop your skills.

Firstly, demos are like training wheels, they help you learn and understand how these construction methods can be used together in a variety of ways in order to construct certain tridimensional structures, but just like with learning how to ride a bike, you won't know how much you know until you take the training wheels out - and then fall on your face. But it's okay, because the next time you try it it'll be easier because you already have an idea of what you should do.

However if you never take the training wheels out, you won't develop yourself to your full potential. As mentioned in the homework section of this Lesson, if you wish to include your attempts at the demos in your submission it should not make up more than half of your total homework pages, so in this case at most you should have submitted 3 pages of demos.

You're not making use of edge detail in your pages, edge detail would have greatly helped you further communicate the form of your structures and how they move through space, but by not adding it they're left very simple, so make sure to add edge detail whenever possible, and remember that only the last step of leaf construction - texture - is optional.

Keep all stages of your construction tight and specific, don't leave gaps in between stages of construction, such as a leaf's flow of line and it's outer edges like in here, these lines must connect in order to maintain the solidity of your structure.

And lastly let's take a look at your textures, which needs some work as it's looking a bit explicit because you often outline your textures or attempt to capture them with generic hatching. You don't design your shadows with a specific purpose in mind and so there are not a lot of clear focal points of detail in your constructions.

So let's revisit how texture in Drawabox is approached, by looking back on this page we can refresh our memory on texture through the lens of Drawabox and see that it is not used to make our work aesthetic or good looking, instead every textural form we draw is based on what's physically present in our reference.

Our focus should be on understanding how each individual form sits in 3D space and how that form then creates a shadow that is cast onto that same surface. Only after analyzing all of this information present in our reference will we be able to translate it to our construction. This means that the shape of our shadow is important as it's the shape that defines the relationships between the form casting it and the surface it's being cast on, which is why we need to consider carefully how to design a shadow shape that feels dynamic and communicates this tridimensional information.

So make sureto go over these reminders in order to solidify your understanding of texture further.

Final Thoughts

In general you're starting to move in the right direction but you're still struggling on a couple of points. As such I believe you will benefit from tackling these exercises again before moving on to the next lesson, please revisit the lesson material mentioned and then reply with:

1 page, half of leaves, half of branches.

2 plant construction pages.
