Screw the haircut, He needs a new finisher. Stomach cutter looks weak as hell.
I know it looks like a stomach cutter with how he excutes it but the premise of the move is that the impact is on 'the face'
I dont see it. If he uses his hand to slam the face down as he is going down, that might work, but his hands is arounds opponents waist. The move just doesnt look painful at all.
Self deprecation is always a good sign when it comes to this. If you can poke fun at yourself you'll be alright and won't get derailed by ribbing.
