How many WIP are you working on? Don't take my advice if you don't want to, but it is better to keep some of your WIP behind the scenes. Wait till the song is fully finished. That will make the final version sound "newer" and showcase all the effort put in. Note I said some of your WIP not all. I'm just saying when you know you have a good beat, keep it under wraps till its finished. Anyway, on to the demo.
I'm enjoying the drums. Sounds clear and hard. The thump adds much to the electro feel. I'm surprised how well the clash of the cymbals added to the climax. If anything to make the cymbals better is to have them panning left and right in line with the kicks. Perhaps also fading out at the same time.
Buildup fx put some more fill. Perhaps add another layer and slowly add in white noise. What makes house music neat is that it builds up to a extreme (for a lack of a better term) "messy" point with white noise, side chained fx splashes, filter rises, etc. and then all of a sudden goes "clean". You do that, but it can be much more emphasized with a better fx rise.
Enjoying the happy instrument used during the buildup. As for the other happy instrument at the end of the song...good but kind of brings the song's potential down. It sounds fine when all the other instruments are going, but not as a solo. Perhaps you could automate the filters on that instrument. Your already going for a fierce style so might as well turn that happy into "saw" mode. (That is a tough thing for me to say since I'm a fan for happy songs...but sometimes too happy doesn't mesh with this kind of theme).
I know everyone is entitled to their opinion. I know previous reviewers have said other things, but I think your build up is a perfect length. Just needs a better fx as I already mentioned. The climax is a good length to me. Among the AP artists, yes you could do the typical repeating the climax for another 4 bars and that will get you popular. However, that will not make your song stand out outside of the AP...especially since you got pros like skrillex, fedde le grand, stefano prada, etc. who by no disrespect to you are the better ones. You can be different by making this more than just a progressive house song that all the artists make. If you can manage to keep the song exciting for 3:30 mins while successfully transitioning at a quick pace (eg. every minute a new theme pops up) you will stand out from the rest. Not even skrillex does that. What ever you do, do not rush this song. Take your time.
Usually I don't say much in a short 1 minute demo. However, I see the potential here and I want you to succeed in what you got. Don't mess it up. :) 5/5 and let me know when the final version comes out.
Bye for now
