Well, it's a really good source choice! For a first mix, this isn't too shabby; I could see this winning in a PRC competition lol.
Speaking of which...you should join the competitions that OCR holds - just in the community threads; should be a new People's Remix Contest round coming up in a day or two. Good chance to get some practice in . Also One-hour compos are every Thursday at 6 or 7 pm pacific time. Could someone confirm which for me? Anyhoo, good luck in your future endeavors
