Yeah, I had a ninja gaiden avatar for a long time. also i used to type completely in lower case letters for years.
I also had a red, green, and black masked superhero in my signature picture for a long-ass time, too.
I listened to the clyp version, which said "new version". I really don't hear that much vibrato (if any) in the sustains, particularly at 1:29 - 1:41 and 1:56 - 2:07. Are you sure it's there? Did you solo the track and check? Vibrato CAN be added via pitch bending, and that tends to be more noticeable, but... I hardly hear any in those time stamps I mentioned. Note that I am not talking about the pinch squeals.
It definitely captures the frenetic sensation I always had in those vicious dungeons! I note that the melody is a little hard to hear at times, like 0:16-0:28, a little balancing may be in order, but for the most part its pretty discernible all the way through. The energy is consistent while keeping me interested all the way through. Nice work.
I find it very impressive that you are able to pull off a mix of two emotionally charged tracks while throwing in the dubstep and glitch! It's intense yet touching. The parts sound pretty balanced to me, and it is engaging all the way through. I'd download it.
I agree that it could use some more variation, but the sound is great. The acoustic guitar doesn't overpower the strings/flute, it's nicely blended. You've captured the original feel of the track with a little extra oomph. Keep at it!
