Nice cartoony style ^_^. I'm not if it's due to the shape of the armour (or if it was done on purpose), but the posture without his armour doesn't seem to match the posture in his armour. I also think he might look better with an ear; or, if his hair is supposed to be long enough to cover his ears, maybe have it coming forward a little more so it's more "free" looking.
He seems to be falling with his armor (too heavy ? :)). Try making his legs more perpendicular to the ground. :)
Hope it helps.
