Hello Esteban90, I'm ThatOneMushroomGuy and I'll be the TA handling your critique today.

Arrows

Your lines are looking smooth and confidently drawn, which helps with conveying the sense of fluidity that arrows carry as they move through space. The placement of your hatching is correctly placed, as well as looking pretty neat and tidy overall.

Overall you've done really well in this exercise and it's good to see that you're carefully thinking through your marks by the evidence of planning dots. As a finishing touch, use additional lineweight on top of the arrow overlaps in order to reinforce their depth.

Leaves

Moving on to your leaves, the sense of fluidity present in your arrows carries over nicely into them, they're looking energetic and flow well as you don't only capture how they sit statically within space, but also how they move across the space they occupy from moment to moment.

Your leaves are also generally bending correctly and it's good to see that when approaching edge detail, you're often avoiding drawing more than one piece of detail with a single stroke.

It seems that you're often adding texture to your leaves in a very explicit manner. You can find here some extra notes on how leaf texture should be approached.

Branches

Continuing on to your branches, they're coming out decently, but for your line extensions, keep in mind that each segment should start at the previous ellipse point, in your homework however you're approaching it by starting your new line around the place where your previous mark ended. This effectively removes the healthy overlaps we wish to achieve by extending our lines, and that's stressed in the instructions.

Remember how branches should be approached, by having your segment start at the first ellipse, extending it past the second ellipse and extending it fully 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 the pattern until your branch is complete.

It's good to see that for your ellipses you're drawing through them twice, this helps maintain their fluidity and confidence. Still on the topic of ellipses, try varying their degree shift more, since currently your ellipses have very little to no variation between them, this causes them to look consistent which flattens your forms.

Plant Construction Section

Onto your plant constructions your work is often coming out quite nicely. Your plants are coming across as very organic, energetic and above all they look very tridimensional.

As with all things though improvement is still possible, here are some of the points that you should keep in mind when tackling your next plants and other constructions in this course.

Make sure that you're constructing all cylindrical objects around a minor axis.

Your mushrooms constructions are looking very well made, although it seems that in trying to capture the complex shape of the cap you have ever so minor inconsistencies which hurt the solidity of your construction.

If we check the mushroom demo we can see that another effective manner to approach mushroom caps is by gradually building them up with ellipses and afterwards, connecting them.

For your pitcher plant construction - and any other which has you drawing small ellipses - remember that small ellipses should still be drawn through twice, fully from the shoulder, if this isn't possible, consider drawing them bigger.

When constructing flower pots, make sure not only to construct the simple overall base of the structure, but also it's secondary forms, such as the rim on the border of the vase that is often found in them, this will help solidify your construction.

In this construction you're attempting to capture complexity way too soon in these structures, becaude you're trying to draw the complex twists and bends in the leaf's outer edge, instead of using the leaf construction method to gradually build up your structure, starting from simple forms and then adding complexity as needed.

For this structure you skip construction steps by not drawing the inner stems with the branch construction method.

Your textures are on the explicit side. Texture in the context of this course is an extension of the concepts of construction, with construction being focused on the big and primitive forms that make up different structures and texture focusing on communicating the small forms that run along the surface of an object, essentially texture is a way of visually communicating to the viewer what it would feel like to run their hands across that surface.

None of this has to do with decorating any of our drawings, what we draw here is based on what's physically present in our construction. As introduced here, we can notice that we should focus on each individual form and how it casts a shadow on neighboring surfaces, understanding how each individual form sits on a 3D space, and analyzing all of this information present in our reference to be able to translate it to our study. The shape of this 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, as such you should design your shadow shape in a way that feels dynamic, as shown here.

This approach is of course much harder than basing our understanding of texture on other methods that may seem more intuitive, but in the long run this method of texture is the one who enforces the ideas of spatial reasoning taught in this course. By following these ideas, you'll find yourself asking how to convey texture in the most efficient way possible, with less lines and ink, focusing more on the implicit mark-making techniques introduced in Lesson 2. Going forward here are a couple of final reminders of how texture in Drawabox is approached.

Final Thoughts

Overall you've done really well in this lesson, you're applying the concepts taught in the lesson with only a couple of minor hiccups and your plants are turning out quite tridimensional due to that.

Make sure to keep the points I mention here in mind and going forward be a little more careful when applying the instructions. I'm going to be marking this lesson as complete as I believe you're ready to tackle the challenges introduced in the next lesson. Good luck in Lesson 4.
