the font for "NEO-GEO" is a little tall. you typically see the "N" letter be almost square. could just be the preview i'm getting though.
maybe try and add a little space between each of the mini marquees to have it match the height of the letters in the middle
also, the MVS system had little windows where the operator can insert the art for the games installed....... maybe try 2 windows on the right with the 3 mini marquees in each.
couple ideas anyways.

otherwise it's not bad at all, good range of games.
