Very Creative

I think you're effort was overall very solid. Here's a more detailed review:

Pros:
- The song's mastering is good; no over-compression.
- Both styles of music you were going for are clearly defined (DnB drum and classical strings).
- It also loops very well.

Cons:
- The song is repetitive. Try creating a memorable melody for each section of the song.
- Also, try branching out instrument-wise. Try adding a piano or something else to take place of the strings in some parts.

Good job, and good luck in the future!
