WEEEE
You asked me to check out your song, so I did and initially, I didn't really like it that much. Feeling like a cunt, I decided to download it and throw it on my ipod so I could listen to it some more before dropping a review, and I have to say, this track has really grown on me a bit.
The echo blips towards the beginning give in to a nice reesy sounding synth, the rhythm is classic. Simple, but classic. It all sounds really well produced too. The sounds after 00:54 are really cool/creative. I love them. The rhythm alternates a bit after that, as do the melodies. I don't think that it got too muddy near the end. I noted what it was you were talking about, but it really wasn't a big deal.
This track builds really well. (I don't know why, but that intro reminded me of envy's heaven remix. It's odd because the two tracks have almost nothing in common except maybe a few of the same notes.) In any-case, I'd say change what you feel like you have to.It sounds good now, but it can sound great. Maybe try adding some atmospher at the intro? I don't really know.
Good luck man!
