I think its pretty damn good, great colors and all good layout - really no tangents ( well there are BUT to the average person who cares )
really the ONLY thing I "may" want to see how it looks differ is makin the jacket and face more black N white, so the goggles and the blue poles POP out more.
BUT with your work ( as with all your work ) I can almost garenty youve gone over colors and every thing..
