Many thanks for your great artwork, hydef.
Some minor things I noticed:
Popeye (Wide Screen) is missing Popeye's picture on the left and the copyright text on the bottom. Both were present in previous versions of the artwork.
Mario Bros (Multi Screen) the upper part of the LCD segments looks more faded than the lower one.
Are you considering to animate the missing animated buttons?
And also, are you considering to "vectorize" the back cases of the G&W games? Some (like the Multi Screen) have a nice artwork on it.
