These are amazing.

I love these drawings! Really groovy stuff. I would say, try to create and stick to the rules of your ginger anatomy. For example, for the guy that looks like he's doing the limbo has two different kinds of knees. His right knee looks like it protrudes a bit (knobby), and his left knee looks a bit more blobby, and more hidden underneath a large quad. Both look good, and we aren't trying to make his knees look symmetrical per se, but if we have a general guideline for how these ginger people should look, we can make them look more real and add more unique character to the form. Just an idea. I think you did a great job :)

Nice work! Thanks for putting the reference images with your drawings, that is a huge help :) You did a great job with the ginger and the seals. I noticed with the more complex subjects like the elephant and the giraffe, the cross contour lines don't quite wrap around the form as well as they do with your other drawings. It may be a lack of overlap. I tried drawing over the elephant to see what it looked like. Hope this helps!

Looks great!
