Hello I'll be reviewing your homework.

Your arrows could use a bit of work as some of them have little depth to them. Pay attention to the edges as they get closer to the viewer. The distance between each edge gets shorter and longer as the arrow gets further and closer to the viewer respectively. I have provided an example of what I mean as in the lesson 2 notes for the organic arrows it is difficult to see.

Organic arrow example

For the organic forms I'd suggest ghosting the ellipses and curves more to ensure they touch the edges of the forms. The forms themselves are alright.

The texture analysis is superb, keep it up.

Dissections are also excellent with some minor hiccups, some of the forms do not have a clear silhouette. I am unsure if it is intentional or a simple oversight.

Form intersections look good though I'd suggest practicing rotated boxes a bit more. Add in organic perspective and rotated boxes into your next few warm-ups and I'd also recommend drawing through your boxes in the organic perspective warm-up (they are not necessary as revisions). And finally, when drawing cylinders the back ellipse has a longer minor axis than the front ellipse. The difference varies with how foreshortened and large or close the cylinder is.

And remember: Always do your warm-ups!
