Starting with your arrows, you've mostly done a good job, though they've some issues.

Firstly, the lines are a little bit wobbly. Like in lesson 1 exercises, you should always be prioritizing confidence over accuracy, and make sure you ghost every line as well.

This applies to hatching as well, take your time with it and don't rush it.

Second issue is that the arrows themselves aren't growing much as they get closer towards the viewer, check this

And lastly, remember you can add lineweight to overlaps to clarify the folds. This should be done with confident ghosted superimposed lines too.

Organic forms

About organic forms, you start doing well, but end up going away from the basic forms you should be going for. Don't forget as well to draw axis lines for the contoured sausages as well.

Lines are pretty confident with the only exception of some ellipses, so good job on that! As a last thing, you're having trouble in the shifting of the degrees of the sausages. Even if the sausage is completely straight there will still be a shifting in the degrees of the ellipses. Take a look at this as it might clarify it a bit better.


In textures you're doing a pretty good job overall; the main issue you seem to have is that sometimes you tend to focus on outlining forms. Remember that you can only draw cast shadows of forms, you can't outline the forms themselves.

Form intersections

In form intersections you're doing mostly a good job on mantaining consistent foreshoretening in the forms, though you seem to miss some of them. Something that helps to improve this is to draw every form with shallow foreshortening, which is way easier to make consistent over every form.

Another thing is that here as well you seem to be rushing the hatching a bit; remember, take your time with each line and place the pen carefully at its start so there is no fraying on both ends.

Organic intersections

Organic intersections in general feels pretty solid and 3d, I can only catch that you're not drawing through your forms. Don't forget to always draw through them even if the viewer can see them.

Shadows run believable over the surfaces they're being casted, and you're mantaining here basic sausage shapes as you should be doing. They also hang believable over the other sausage, so good job on that too!

I'm only going to ask you to do 2 pages of organic forms. One with contours and other with ellipses, to make sure you understood my pointers. Keep it up!

Next Steps:

-1 page of organic forms with contour curves

-1 page of organic forms with ellipses

When finished, reply to this critique with your revisions.

I tried to exaggerate the degree change in both contour curves and ellipses I hope it doesn't look like it breaks the perspective.

That's better! You still have some forms that are a bit pointy on their ends; remember that their ends are balls, so they have to be rounded, but other than that you're making solid progress. Ellipses and curves get a bit wobbly at times, so don't forget to prioritize confidence over acccuracy.

I think you're ready for lesson 3, so I'm marking this as complete! Don't forget to keep practicing the exercises on warmups.

While I have a massive library of non-instructional art books I've collected over the years, there's only a handful that are actually important to me. This is one of them - so much so that I jammed my copy into my overstuffed backpack when flying back from my parents' house just so I could have it at my apartment. My back's been sore for a week.

The reason I hold this book in such high esteem is because of how it puts the relatively new field of game art into perspective, showing how concept art really just started off as crude sketches intended to communicate ideas to storytellers, designers and 3D modelers. How all of this focus on beautiful illustrations is really secondary to the core of a concept artist's job. A real eye-opener.
