Excellent! Sounds like the build up of an awesome trance track! I have to admit a wasn't a big fan of that last bit where all the energy kinda fades away into darkness, I do like how it sounds like you reversed the instruments it gives a very ominous vibe, the highs are too dominant in this part it kinda hurt my ears, I would recommend cutting the high end on some of the reversed strings? (instruments) playing here.
Other than that Im really looking forward to that beat drop ;)
Peace bro!
