I won't lie, this was pretty good for a test and your 1st animation. The animation and the sound effects were all on key for the most part. Though at certain frames with one of the street fighters, there was this white line next to him. Be sure to always check and erase any white lines when dealing with your sprites. Just a nitpick, but some music would've been nice to have. It'd help make your submission engaging. Since this is a test, It's not a good idea to be putting tests under judgement. These types of submissions would get a low score if not blamed. There is a place called the Dumping Grounds where you can post tests at. It is the button next to your message button. And with it you can show your movie off to your friends, family, fans, etc. So please use that next time. But even then, I think the submission will hold up. You got a long way ahead of you, and I hope you improve and evolve as time goes on. Good luck!
