I posted a part of this solo some weeks ago. Since then I've been working on it in and out, because I wasn't feeling totally comfortable when I tried to speed up. I decided to stop practicing the solo and include some picking exercises in my practice routine to strengthen my technique a little bit before trying to speed up again. Now I'm back on track again and feeling much more confident. It's still sloppy, but I keep trying. Any constructive critics to help me improve on this are welcome
