Improv in F

Hey guys, I recorded this little improvised tune after getting back home from work today.I missed some notes here and there (the beginning's messed up as I had to switch to the sound recorder app), I didn't put enough/any vibrato on the higher notes, the timing is a bit off in some places and I overused one riff, but other than that I'm quite happy with it.Please give it a listen if you have a minute or four to spare. I'd appreciate some feedback from more experienced players (I've only been playing for 9 months and only 4 using solely tongue blocking).

Cheers!
