Thanks for your imput, Jamie!
I won't comment on my little melody (AKA crap), so no one will think I have a bias against it.
Price's idea is an arrangement of mine...? I remember hearing it.
If Virtualshock's tidbit had a strict melody inside (I could fix that in a jiffy), it could be really cool!
Enigmus has a nice intro! Very strong and triumphant. It ends at about the right area to introduce a new melody, too.
Spectrum's could also use a definite melody, but it could also be turned into accomapniment by simplifying it somewhat... that's what I think.
I think Dev's little tidbit could be used to develop a motif of some sort... IE, four notes of fanfare, drum solo, fanfare again, drum solo, which then gets layered on top of by various other drums, and an older melody is reintroduced (or the recent melody is repeated in different orchestration).
I hope I made a difference!
