Try to develop some sort of vibrato. Especially with an extended scale guitar, longer notes can have a tendency to die out early without some sort of vibrato. It's not really an advanced technique, but it's an important one for anyone wanting to make their own name as a soloist. It's just my opinion, but I think these would sound more professional with a little vibrato. Think of it like seasoning in a culinary dish - there are lots of different types that work to different effect, but with none, the overall impression can seem bland.
Also, I know you are recording some really difficult pieces here, so please don't take this negatively, but there are little bits here and there that could maybe use a little tightening-up rhythm-wise.
I'd say it sounds like you've got a knack for doing crazy stuff like Dillinger Escape Plan or Between the Buried and Me. Have you thought about getting together with a few like-minded musicians to make longer songs out of these ideas?
