Cool you use the same sample library and software I do!
Really confidently written and engaging piece of music, coherent from start to finish. Good stuff!
From a production point of view: I thought the mixing was solid in this piece for the most part, crisp, easy to pick out individual instruments though at times it sounds a little narrow, particularly at the louder, brassier, percussive parts. Could've pushed some of it out to the wider channels to give it a bit more 'boom!'. At 0:57 as well, I feel it was *begging* for a stronger bass presence to really drive it home.
From an arrangement point of view, lots of different instruments to keep interesting, obvious string ostinatos to help bind it together, I like your use of the clarinet as well, and the piano towards the end is really nice. In fact I think the ending and the beginning are my favorite parts, lovely little progressions, chimes and glocks give it a nice feeling. The only drawback is the lack of that intangible little something, a core idea or hook or whatnot, that makes it transcend.
Good luck with your future work. ~ mB
