To critique the set as a whole that you uploaded. Eugh. Yeesh! The faces bend inwards and the forheads are really big. The eyes rarely are the same size, which all comes together to form are rather ugly alien looking thing. It looks like you’re trying to use the way you’d draw a pony for this and it doesn’t work. The face sticking out like a muzzle does not work on a human, it just makes the face look like it caves in. The eyes though, I don’t even know. I have torible with them myself pretty often but in some of the images it looks like instead of angling them, you just shrunk them. Needs quote a bit of work on getting that style down.
 
I’d be interested to see how you do bodies.

Dem light blue party eyes!
