If only i could teach you ^^ since you're still using sprites, i would suggest using Flash 8 and the V cam tool (search for it on google and it should also tell you how to use it). It makes sprite animation alot easier
to stream music click on the frame you put the music on in your timeline and go to properties, then click sync and click stream because right now your music is on event (which is what your sound effects should be on)
Use the newgrounds preloader next time aswell. It makes the flash look more legit
