Humm its a good but it just seems a bit flat. The upper body is done brilliantly imo but it could use some work below the waist. The knee caps seem to be going past thier normal locked postition when your leg is straight. I think this is more prominant on his right leg. Shoes could also be better,no offence but they just look plain crap - sorry -. I reckon the shoes spoil the over all image.
Good Job though.
