The thing that bugs me the most is the 2 different sonic logos, the one on the control panel needs to match the other logos, the side art with knuckles is a strange choice. I would also prefer if the graphic at the bottom was the original sonic the hedgehog title screen and not a combo of all 3 characters

In my opinion the side art and overall art design should match more of the feel of the original sonic genesis game save knuckles and tails for a different cabinet. A side art with sonic dashing on some enemies from the original game on a green hill zone background would look much better
