Mix-wise the bass sounds a bit soft (muddy I guess) and boomy to me. Composition wise, I’m not too sure about it. The beginning effects are very dramatic but then it mellows out with the piano. I don’t find the piano melodies very appealing, they meander along and just don’t have much going on in the way of good melodies to me. Conclusion is that I’m not convinced about the composition. Could well be that you can make a good track combining those dramatic parts and more emotional strings and piano, but I don’t think this was done that well.
That’s just my thoughts based on one listen, other opinions may be available.
