Your guitar playing seems pretty good. I would place more emphasis on that. It's really trippy, which isn't my thing but if thats what you're going for then thats good.
The drum stuff on 232 is pretty cool.
I don't think they're anything you need to change, just try to improve upon what you've already started.
Well, getting an actual group together would help you get your stuff out there in terms of help promoting and shows, but that has nothing to do with your compositions.
Crit for crit?
