These look really nice, but just out of curiosity, why are you keeping the Bally/Midway and Atari logos next to each game's logo? It makes the art look just slightly less 'clean,' and since Namco developed all of the games (Atari and Midway were just the US distributors) it doesn't make a whole lot of sense to keep them on there. It's akin to, say, giving Disney credit for Miyazaki's films because they own the rights to publish them in the US.
Of course, if you're just doing it for nostalgic reasons (because you remember seeing those logos on each game's cabinet or whatever), that's cool. I just wanted to make sure you weren't confused about who actually created the games.
