Ok Lagrom!
Here's some comment:
The first thing I want to say is: WORK ON YOUR TIMING!!!!!!! I've herad only two crossovers which were timed well, the rest was out of the rhythm...
My advise is, figure out when the melody sample or beatrhythm starts and count 2x 8 or 16 beats (or 32 or 64 whatever, everything with 16), you will find this rhythm in every trance track and when you carefully listnen to that rhythm your mixing will be much better timed

The build-up and trackselection is very good, really no comment about that!
Good luck with the contest m8!
