This one is the weakest from the 3 I've seen from you. You had one wrong scale (0:16 - 0:17) many notes were not in the scale. I am sure you know how it should sound but you just didn't execute it right. Some other lines were a bit dirty as well. Your rhythm placement should be much more precise. Every phrase has to have some kind of logical finish (on the right beat). You are either too early or too late. I think your picking is on a good way to become nice, fast and clean. Practice scales slowly and speed up everyday like 5 or 10 bpm.
