yes..I agree the mix is thin and "tinny" sounding.....most notable on stuff like the snare... and the guitars. It sounds like some freqs. got scooped out. I'd start twiddling some dials and see if you can bring in some lower midrange, upper bass...or whatever. If they are not there to begin with, or very minimal, I don't think Eq'ing is going to work, however. If you did something in your mix that created the thin sound, then maybe it can still be corrected. As an experiment, I put a pretty HEALTHY dose of additive EQ around the 250-350 range and it seemed to thicken things quite a bit. Probably pretty horrid sounding on other systems, but on mine it helped a lot.
The synth sound at 2:05 was also especially "screachy" sounding. The fade out lead sounding much better, but had a distant sound to it.
nice tune and melody lines, as well as the lead guitar solo which I liked a lot.
