Okay, so I've made this dog (he didn't start as a dog, but I won't get into that) and was looking for a little C+C.

My goal here was to keep it simple, but still recognizable. I'm also working with the 4-colour GameBoy palette, as I'm fairly new to pixel art and I'd like to start by focusing on the pixels rather than worrying about colour theory (at least until I'm a bit more comfortable with pixels, as I do like colour)

So please help me improve here. I really appreciate your criticism, and the time spent to take a look at this and give feedback. Thank you.
