Character concept

These are some character sketches I did. I gave more emphasis on designing the face, I feel like there's room for improvement ,but i can't get my finger on it
So, the biggest issue I see with your designs is the lack of dimension and structure. Just because something is cartooned, doesn't mean it doesn't adhere to the same rules of structure (unless it's a very stylized design).
I did some sketches to show you what I'm talking about, I hope it helps :)
