Thanks for the quick responses, guys! I'm glad I posted here before daring to attempt a submission. The rendition of the main melody started as something I was doing for laughs, but a friend suggested I try to get it noticed here on OCR, and here I am...
I do plan on extending the song with an "Act I - Act II" sort of thing, in which I intend to add a bit more of my own personal flare. I'll definitely be taking my time to polish this up a bit with all of your creative/mixing suggestions in tow.
Thanks again, and I'll be back with something epic!
