I thought about adding three triangles on the left but I decided I wanted a symmetrical look. I tried to line the pushbuttons up to accomodate that feature.
As for the top, I had large spot of text that read "McClain's Arcade" but I opted to take it off. I'm not exactly sure why... Maybe I'm lazy? Once I actually attach the overlay there won't be much shown on the topside of the print. I made it that large as a safety measure in case my bezel doesn't line up as I anticipated. But yeah, it probably would look better.
