I love the warm colors. The face is fascinating, it seems to just jump right out of the picture. (burn tools blah blah don't change the face it's perfect) It's true the light source is vague but that does not seem to be terribly important in this piece. What does bother me is that the visual path your eye follows goes down toward the pumpkin and cat and they both look unfinished. I'm not saying outline everything in the pumpkin and the cat just put some line work and more detail into it. As it stands it looks like it's in the same field of view but it's out of focus. When you draw water on the pumpkin dont actualy draw the whole outline of each drop. Just draw the highlights of the water.
