Good for a first try - but here's some tips.
-Shorter clips. Don't need to see all the reversals to set up the move/highspot - just the spot itself.
-Less entrance footage.
-Break the song up, so that the clips can be synced with the song. Like, if there's a repetitive beat that can be broken up into 3 second parts - do that first, and then make your clips fit in those intervals.
-If you follow that rule, you should get everything into one song - which is for the best. Using 2 is bleh, unless the first song is an intro to the video.
Those are just *MY* rules when I make a video. For example, they can all be seen in play here - and old IWS intro I did.
