nice attempt. :)
You really need to watch out for dwarfing.. its a term meaning that one of the character's or all of the character's limbs are way too short. the one closest looks pretty good but the one hidden, still needs to be the same length. I would suggest bring the knee up on that one too if you were unable to fit it on the paper or on the screen??? The only reason I gave you a 2 is because since you are doing fan art you have excess to reference. don't give up it was a really good effort.
