Very nice sound piecing, well produced and it flows well. Not sure I'd put this into Progressive Rock myself, but certainly compared to most modern popular music it qualifies as such pretty easily.
I agree with some of the comments above on the cymbals. I understand why in such a fairly sparse arrangement they tend to be used a lot to provide a sort of backwash. But, at least on the crappy speakers I'm listening on, they are a bit much here and there. Maybe not too much, but maybe too much presence in them. They don't really interfere with anything else really, but maybe just call too much attention to themselves.
Normally I'd not bother mentioning such a thing, but obviously this one got a lot of production attention, so I figured that such things are probably important to you.
