Neat
I didn't quite like the piano selected for this one. And instead of the note resonating, it cuts off pretty drastically, especially clear in the beginning. I would really advice using the reverb effect for future classical/hip hop fusion songs.
However once the strings and synths start going at it, it really starts to pick up. The hi hat issue has been resolved so that indeed make me quite happy.
That choir man... it would sound so damn good... if only you had found a better choir for it. Goggle Papalmedia choir, it's an excellent free soundfont for choir.
Reverb the choirs like crazy, choirs are only good if you reverb them so hard that their mothers start speaking reverbed!
Otherwise a very interesting mix, it's just the samples you chose this time around that kinda perked of me ears.
Still, good work Yumbo, keep going, you will get as far as you want to.
