Looks like you weren't the only one replying a little late, haha.

Overall, I think you've done a good job at conveying the forms of the animals that you've redone. The main thing I want to bring attention to is your line work. It's really important to have clean lines, as they allow you to better convey an object's "3-D-ness", as well as making techniques like adding a boldness to your lines more convincing.

Good luck on whatever you may pursue in your life!
