I'd like to point out 2 things here

1. all of your constrctions are lacking line weight and shadows filled in with solid black, which makes it really hard to understand how these parts exist in space. Your elephant is an example of this effect, as I can't make out the forms with all the noise. If you dont have a brush pen or thicker pen to fill your cast shadows with, still fill them as solidly as you can with the pen your using. A half-hearted effort will just create a focal point and draw your veiwers attention to it. Uncomfortable mentions that in his cast shadows video. If your worried about your pen, I tried it in lesson 2 as i didnt have a brush pen either and it did get use up faster, but the clarity and understanding it gives is well worth it.

2. this is something you can take with a grain of salt as I am currently working through this lesson myself. You constantly added forms to your bluebird construction, which isn't a very good idea as it adds noise and breaks up the bird as a whole, ruining the solidity. Try to stick closer to uncomfortable's method and imagine that your merging your forms together. Sorry if that comes of as a dumb platitude but it's the best I have.

good job forging through though

edit: I looked at your sketchbook and I think you should focus on your warmups and understanding each task and the units of work they consist of

Hi Allipses — 

My name is ariejamesdallas and I am offering a volunteer critique. I'm also studying with Drawabox.

First off, congratulations finishing this lesson. It's a biggin!

Moving on to your Organic Intersections you are drawing with confidence! I especially see that in the contour lines you are wrapping around the sausages. You also have your sausages oriented perpendicularly which is helping to make them appear to have weight and volume!

To go further with the Organic intersections I suggest you fill in your shadows in completely. It will help sell the appearance of real weight and light. Try filling in the ones from your homework and see if you can tell a difference.

As far as your animals are going I wanted to compliment you on your drawings where you are taking the time to do individual strokes of fur/hair. I see this on the bluebird drawing that you aren't just copying the same pattern but rather have some feathers swoop up while others swoop down. At other times you do appear to get rushed with the hair, like the gerbal drawing where the hair lines are not fully coming together which is making the illusion of tufts of fur less real.

In your constructions I can see that you are following the process of first building a primary structure composed of ribcage, pelvis, and head. Nice job keeping the forms for the head/ribcage/pelvis simple. As you build forms on top of the primary structure, there are drawings where I'm starting to get the sense of wrapping forms, such as the elephant legs. Or the the muscle that you attach to the legs in the cat drawings.

In other drawing I feel like your forms are not wrapping around the form in a convincing way, and appear more flat, such as the elephant #1 head. I think you have the basic idea of the lesson down, but I think you can push it further to really get a better sense of illusion. Remember each piece that you add to a mass you already have drawn, is it's own little 3D piece that while separate, also adheres to the primary form underneath. This is the whole concept of making things look like they are wrapping around eachother.

I hope this critique finds you well. I've left some suggested revisions in a separate place.

Keep going!
