looking good!
I take it that is a playhouse in the background? Or do you live in Ky?

My suggestion at this point would be to leave enough room between player 1 and 2 controls to put a trackball later.
Chances are you will want to add a trackball at some point.
My first cabinet I did not leave enough room for the TB, even though it was a big panel like the one you have laid out. This spring my project is to re do that CP to include a trackball and maybe a spinner. I will have to remake the entire panel.
You may want to go ahead and install a trackball now. It would be a lot easier at this stage.
Here is a blog I kept on the third machine I built, might help you out...
