Help me out with decisions about a young justice arsenal custom. Read description

Please comment!

 

Had this idea for the robot arm to be a seperate piece you clip in to a stubby arm. Not quite sure I like it or not so I would be very happy to hear what you think. Should I go on with it? should I just paint on a regular arm? Or do you have any ideas of other ways to connect the robot arm to a stubby arm piece?

 

Also should I give him the 2012 hawkeye hair or just leave him bald? Or do you have any better options?

Done
