It's not the shooting for me, it is more likely to come than not with time. Especially if they are catch and shoot opportunities.
My biggest worry is the lack of seperation. I thought that overdribbling was a simple fixable issue that needed to be outgrown. Now, I think he is busting out moves for 6-7 seconds just to create an advantage because he can't break down defenses consistently. It really hampers his potential and limits him to be a secondary ball-handler off the bench and that's not very alluring.
