Hey Peter. Those are some ridiculously good tracks in my opinion. I spent a good chunk of time browsing through your website. That stuff is very well put together in my opinion.
When I a/b it to similar content on a good pair of monitors, I agree with Nate that there's a definite difference in the low end, but it shouldn't be a hard fix. I would love to give some more detailed thoughts on this, particularly with the balance of voices in the middle section, and the way the synths are layered into the rest of the composition, but its hard to do without pointing to specific min:sec markers. Can you post that track as an mp3 (even if it has the "bonix music" still in the background)? Or maybe put it on soundcloud just so there's a counter on the playback device?
...also, can you tell us what you're using for reference mixes (if any) and what your main VI's were for this? That might help too.
