Not too shabby.
When it comes to SF sprites, I think the benchmark is MK v SF. Though yours not nearly as epic, long, or well choreographed, I still believe this is a great tribute. To start, your choice of characters was awesome. I love seeing different people instead of Ryu and Ken all the time. Also, you had some good fights in there, and your spritework was wonderful. To improve, make the combat more intricate and involve more complicated moves to catch attention, and possibly add a story. Overall, not bad, it stood up on its own. Good luck to you in the future.
