Thats some heavy sh*t!!
In the first one it sounds like the guitar goes a little flat tuning wise to me. I didnt analyze it too close, but something sounds out of whack.
The second one with the cool riff, the guitar sounds real thin to me, It doesnt have any balls to it. Sounds like a preamp preset or something.
But overall you got some happenin stuff.
Does the young one want to play with you before you start putting something together? I guess I would try to look at the situation in the 3rd person. If you are an authority figure to this young man it might put you in a too friendly place with him.
Good Luck whatever you do and keep hammerin!
