OK. So I've decided on 2xSupers for the 8-Ways and Happ Ms Pac-Man/Galaga Replacement Joystick for the 4-way

Now I need to figure out how to lay them out. I've done up a rough sketch of what I have though I'd like.
Does anyone see anything wrong with this ? Anything you 'just don't like' ? Colors hurting your eyes ?
I do want the 3 joysticks instead of using a T-Stick.
The panel is for vertical games only.
Shooters and classics I guess.
