Nice start! I like the sound of the synth and that dark vibe at the beginning. Buildup is good but could maybe use a bit more variation and a more work on the dynamics. The mood jump, when the piano is cutting in around 50 sec, is interesting. The breakbeats afterwards are pretty cool. I usually like the mixture of electronic stuff with orchestral parts but here I have the feeling that the strings, starting around 1:30 don´t fit into the mood of the track. Especially around 1:41 they are tonally a bit off.
Since this is a review for a review - review, I try to be a bit more critically than in just a random thrown out review. In my oppinion, you have a nice start here but not really a full track. The ending is very abrupt without and cadencing or dynamic swelling beforehand. A fadeout would already help a bit, although people always claim a fadeout is a no go.
Also the track is a bit repetitive at the moment. There are mainly two parts. The nice build-up at the start (which I really like) and the DnB part after the drop. In both parts you basically loop a single chord progression. There are a few simple tricks that can easily help you to give the track a bit more variation. An easy trick is just to tranpose you whole track by a few semitones. You will see that, depending on how many semitones you transpose your sequences, it will give you a very different mood. Transpose everything by one semitone will give a very dark mood for example. Then you can mess around with the chords. Or transpose everything from major to minor (or vice versa).
Finally, you can play a bit with the dynamics. For example: Fade out various instruments and make a drum break. Afterwards you start building up again, or bang: Just cut in with all your instruments after, for example only your piano or strings were playing. These are just some ideas...
Sorry, I cannot say really much about the mixing here. My headphone cable just broke and I just listened to the track over my cheap speakers.
Keep it up!
