I love well made loop techno.
But in my opinion. If your loop doesn`t change, why waste vinyl and recording time, and just make it a lock. Then the DJ can do everything.
But to make one loop and record it for 5 mins is nothing to do with taste, and more to do with laziness, or lack of ideas, or at least that`s how it appears.
It`s interesting changes that make people freak on the floor, little edits, chops, cuts, reverse, sweeps, drops, flange etc.
You don`t have to go overboard, but take a look at the music by the true loop technitions like Simms and Speedy J, and note the changes. then listen to the crap that gets churned out on the millions of short lived labels from germany, and you can see why those at the top of the game are there.
You can hear the effort and care, and work behind the tracks.
So much can be done to just a single loop, to make it interesting.
So composition IS a part of production critique.

As for your production, I think your problem is that using Reason exclusively means you are using the cack eq on it. So the production will always be a little sub standard to a point.
Export the audio to another sequencer and you can EQ more effectively.
