That's crazy - I got to see the early stages of porting before going to bed, and now after waking up it looks like you've already finished?! Is there a speedrunning category for SF pixel art that I didn't know about?
You should try to do it yourself, the map sprites are easier than the others, there is also a version of me in the sf2 section even though it needs improvements, maybe it will serve as a basis for the map sprite.
