Good Paint
This is a good colored up sketch but iit needs more of a background... the character itself is drawn out well and has a good use of shadows and shines to it. The position of the Lucario is a standard one so it is good you were able to work with that...id use less black lines in the future to give a more blended look..you mentioned this as a speed paint so i am not sure how much you contributed but more details next time is best
~~THINGS TO IMPROVE ON~~
Give this a nice background and maybe limit your use of the black lines to blend things better
