Excellent work! Would you be willing to tackle the back art as well, with the lightning and everything? Also, do you have any plans for restoring artwork for the first and third games?
I've already put together a map to restore the SOR 3/BK 3 cover. However, I need to obtain scans of the Bare Knuckles 3 Manual. I did restore Streets of Rage (Japanese artwork) for the purpose of making covers. When I did it, I didn't think of posting the final image as I did with this one. It was altered and down scaled when I worked into the Genesis template. I can see about find the original image if you want it outside the Genesis cover art.
