A little bit raving just what I like! Stay on this way! Maybe try the same setup but a little bit... dirty with some tubeDistortion and try arpeggio on the 303 you can make some crazy sounds with this! Peace! :)
I would change the 303 pattern a lot more, it gets monotonous. I like the perc in here, the pad in it and the way you modulate the 303, try experimenting with the other synths too though.
