I think this is a pretty damn good piece you've made here. I like it quite a bit.
Pro's: Everything blends well together, you've merged a nostalgic electronic sounds with a DnB piece, it sounds like you took your time with this and did not rush anything and everything was mixed well.
Con's: It sounds like some of the sounds are out of place or are not lined up perfectly with the rest of the music. For instance the sound that comes in between 1:41 and 1:42 sounds like it should have been just a tad bit sooner than it had been. One last con is the "bomb dropping" sound at the end of 1:19 it just sounds a lot lower quality than the rest of the music and takes away from the rest of the music at that point. I do however like the idea of using the bomb drop sound to move into the next part of the song. It's a great idea just poor execution.
I know it may seem like a lot more con than pro but I still think it deserves a 4.5 star rating.
