Digging the intro a lot. Every time I hear some progressive house I tell myself I gotta make some, and then I never do... but that's besides the point. I can't believe I'm saying this, but the drums might be a little heavy for it. Have you tried just a kick?
The melodies that come in are nice, but they sound a little harsh over the smooth track. Maybe straight up lower them in the mix, and get some slightly smoother synths, and a touch more sidechain, at least until the little build up. During the buildup to 3 minutes the lead synths sound great.
I agree, don't be afraid of reverb.
