Thanks for the comment cracked! Really admire your work ethic, as always.
How were you starting those thumbnail sketches? To me it looks like you got into the details a bit too fast. might be a good idea to start with abstract shapes and mess around with them until a nice composition is found. One other really nice exercise I was doing once is called notan, in it you create the image using entirely flat black and white shapes. This forces you to decide what is seen as light and dark, and makes you figure out ways to have everything in the image clear and readable since you're seeing it in the simplest possible way.
And little suggestion based on your boxer drawing, when you're hatching like that try to stick to fewer line directions, and don't forget the hatching is supposed to give value information too. In that pic the hatching makes everything look about the same value.

Keep killin' it dude
