Wow, great job - you've definitely nailed the smooth jazz style. I think your tone is great, you play with a lot of soul and conviction, and your improv develops nicely at the end of the recording.
If I had to say anything:
- it might be good to use some additional dynamics and phrasing to build the intensity from the start of the melody to the end. In other words, perhaps you could start playing the melody a bit mellower and then build up towards the end, tell a bit of a story.
- some of the melody is not played in exact unison with the guitar, which can be cool, but in some cases here it doesn't sound entirely intentional
- there are some intonation problems in the altissimo register (I think you might be able to get away with some subtle auto tune just on those notes but don't tell anyone I said that)
- At around 1:20 and 2:43 there is a bit of a note flub
Otherwise, I think you're doing some great work here (esp for a first take!) and with some polish I can see this catching on.
