ok heard it, here's my comments.
Very easy to tell that you're quite new at the blues, as there is a lack of attack and some of the notes (vibrato) were out of tune.
Your phrasing seems to have lots of potential there, so thats good, just need to concentrate on the feel of the music.I agree that you sound a bit careful, try playing it again over and over with your eyes closed...it will teach you to feel your scales...
Here's a trick you could use, record your guitar solo with as little volume as you can hear, say maybe using half of your headphones when recording....,Sometimes when you can hear yourself whilst recording a track too clearly or too loudly, you become a little bit more cautious.
all in all, its a good effort, listen to more blues greats and try to incorporate their phrasing and attack into your work.
And yes, you're gonna hate me for this cliche, but you need to have more feel brudder, imagine yourself expressing a message with your solo, where words fail and only the guitar can speak of whats in ur heart.
