My ears...
...are almost bleeding. You probably weren't expecting praise on this, but seriously, polish up your skills before submitting a solo of one instrument, especially a wind instrument. Though I must say you went through the whole song without fucking up too badly. Well, I'd suggest practicing your beat. The sound is quite good, but the timing isn't there at all. That part around 1:30, it's quarter-notes, and you play them as if they were only halfs, with a huge pause in the middle (which isn't on the partition). There are quite a few other noticeable mistakes this and there, such as at the beginning. I play the sax myself, and quite frankly it's a very easy instrument.
Well, your tone is quite good, but some notes were wrong and most of the notes weren't timed correctly at all.
If you plan on submitting here, then at least make your own work, not a crappy cover of an overeasy song. Try throwing in more instruments, too. That'd be nice.
The score is kind of making me lie, though. 186 votes = 4.21
