There was a pretty rough bend a little past 3/4ths of the way through. Your sweeps sound about 80% cleaner than your alternate picking, so I'd personally work on reversing that. You have a pretty decent vibrato going, although it might not be a bad idea to work up a few different vibratos, since the "slow and wide" won't fit every bill.
Overall, it sounds pretty decent. My laundry list would be:
1. Alternate picking
2. String bend control
3. Varied vibrato.
I like the wah work a lot!
