work on your vibrato man! it's what separates a good from a great player. Your tone could use some polishing as well to make it sound less tinny (it needs warmth). I already posted the link to my cover in your other thread, I'd appreciate if you looked at it.
I agree, I was trying to work on the whole Volume swells and Vibrato at the same time. Tone wise its mostly the camera mic's capabilities. Since I shot this ive been working more with eq/reverb in mixing.
