You are and excellent artist. I wanted to critique one of less whimsical pieces too. First off the eyes really pop out at me. The lighting in them gives it great dimension. There is also a lot of feeling in the tigers face. I applaud you for doing the tiger in this position. I always find it really difficult to draw animals changing direction or with curves in their bodies like that. I would say that if your light is going to be that bright the shadows should be a little darker. Other than that it is a great piece of work. I am curious about one thing though. Is the tiger's ear supposed to look ripped? If it is that is a great way to give your image a story in one frame.
