Oggie Boogie Blues!
That's an excellent in-progress work. Working on the visual shouldn't be too much of a probleme for you. The sound quality of the singer can be easily fixed by increasing the "Audio stream" and "Audio event" at their maximum when exporting your flahs or/and by re-recording it with a better mic.
The most difficult you'll have to do is to find the music of the Boogie Blues WITHOUT the original lyrics. If you have some talented friend, or know how to do that, you're lucky. Otherwise, you should try to find someone that could be abble to do that on forums and stuff.
Good luck and do not give up! You have potential in FBF-ing and in overall animation as well! I saw "Chase this Light" and I can tell you you'll go far!
