Adopts!

Ummm.... okay, where to start here?

First off, the art looks lazy, and barely any detail was put into it at all. At least put some effort into what your advertising.
The first one looks like something that just crawled out of Hell, the second looks like a type of mermaid/ cat hybrid, and I can't even make out what that third one is. If it's supposed to be an egg, well you did a pretty bad job on it.
What I would do is flesh out the adoptables more, and give them black outlines to know what's what, to give them more of a defining angle.
I really hope you do better when it comes to adoptables.
