Cool clips, struggled to get through song 14, but song 17 is cool especially the first minute. Track 18 was ok as well but well feels very pentatonic, might just be me. You have a very nice tone though and a very clean technique.
Few points on criticism, first play with a metronome. Even its its with head phones your pieces have very *elastic* timings which i don't think was intentional and you speed up toward ends of phrases (this is normal btw we all do it) and having a metronome will help this.
Imo besides song 17 the other two sound line noodlings, mainly due to the pentatonic feel of them. I'd be cool to see some of that jazz theory come through, sit down and think about what your gonna play.
Last point is to write complete songs. Now i know these are just ideas and clips but a few really have some potential. Again its structure and thinking, set the song out practice with a metronome.
