Robotic knight concept art

still working on my rocket knight fan game i am not going to show off any new content until i am happy with the game which i really am not at the moment you see the game was my FIRST EVER gamemaker game and because of that the programming is just broken I made it stupidly complex I am going to have to start from the beginning again fortunately I still have all the sprites left over anyway back to the game I have been doing alot of doodles and concept sketches in my spare time and one of the ideas I had was ROBOTIC KNIGHT! basically I took the idea from metallic from sonic a robotic clockwork rocket knight I did a ton of little sketches 2 different designs which do you all think is better?
