? you have many mistakes in his body, and in some questionable random parts: his left hand is shorter then right, his swords is on the air not in his hand, his face does not say much but that he is looking at oblivion and not expression of victory. what is the spike doing on the air, left of his hand, no shadow to make it it part of the ground. also be consistent with details and position of composition could be better. too heavy on the bottom right corner.
i am sorry but how can you fix your mistakes if everyone says how amazing this peace is and ignoring major mistakes... you want to be better then be better by focusing on consistency and rules
