Hi

your organic arrows are a little bit impecise and also the ellipses of te organic forms. Remember the exercises from lesson 1: draw your lines with confidence!

The inclinations of the ellipses of the organic forms are the same, you haven't thought about your forms in 3d. when you draw be careful to think about the perspective.

your texture analisys and dissections are pretty good well done!

In the texture analisys don't be afraid to use shadows, use the black pen to cast more shadows.

and in the dissections try to draw more deitail.

the form intersection was very well done good job.

the organic intersection were unconsistent. all the sausages don't have weight, they have the same form.

the shadows of that exercise do not have too much problems (try to imagine all your drawings in 3d it will help you a lot!!!)
