mmm...
It's a very smooth ambient piece, and I like it.
I'm assuming that the odd pauses here and there are just small mistakes on your part, so I'll overlook those. I would award a ten to you, except for one small thing: the harsh chords at the end. You may want to revise those chords - they sound out of place with the rest of the song. Also, this is really up to you, but you might want to consider rearranging the notes of your arpeggios a bit just to provide a bit more variation - play the same notes, but in slightly different orders.
As for the white noise, you can get rid of some of that using Audacity. I believe it's a free download, and it's made by Propellerhead, which is the same company that made Reason. Search around a bit, you'll find it. Then just play with the filters until you get rid of as much of the white noise as you can.
4/5, 9/10, nicely done. Good luck with the MMORPG, too... I'll have to check it out.
Power to you, RyeMcCrory!
