To be honest, the drums up until 1:14 were not working at all. They were obstructing the Sytrus strings, real or not. Try to think about the purpose of each instrument in the mix. Drums are there to lend rhythm, not be in front, even in a Drum 'n Bass song. Even Drum 'n Bass songs have breakdown sections where the drums are a bit softer than the rest of the instrumentation. I think you can do much better than this. ;)
The bells in this mix seem a little dry. Maybe adding some wide reverb or stereo delay on them might have helped. This mix is also kind of repetitive with basically the same three notes playing over and over again in the square wave arpeggio (with some variation but not much).
When making songs, try thinking of ways to keep people listening. Listen to your own songs objectively and think about when a person might find a song would get boring. Then figure out how to keep their attention. ;)
The lead isn't as expressive as it could have been, as it was just a triangle wave with no vibrato, whether with a quick or slow attack curve, but everything else was pretty good. The snare is prominent.
Around 0:59, though, the kick seems to get lost in the reverb. The low passing hit at 1:20 was also a bit much in the highs for me, but that's alright.
You did a pretty good job with this overall though, keep it up. :)
