I like this one here, because this one has a cute element to it. Nothing too fancy but simple and clean and straight to the point. The eyes are the best part and draw in that "CAT" like facial features to this character. The orange seems to be your go-to color in terms of the spectrum here. I do like the small wall the character is leaning on, almost like it is stuck there and wants to be free. I do think you could add another border to this one, so it has a more completed look and less white space around the character itself. Other than my words of help, this was a good one and glad to see another character.

Just add up a border to this one and I think it'd really complete it.
