Riff 1:
Around 0:46 you made a change that I really like, you do it again at the end. To me that little lick was what stood out. Felt a sort of pensive mood on this one.

Riff 2:
Seemed like an instrumental piece (the other one sounded like something that you might want vocals with). Might be interesting with a distorted lead adding some harmonies.

yeah the first has 2 different tails to it, I always kepy coming back to having it that way, it just sounded more suprising to me, kinda like it made your ears perk up cause you weren't expecting it, and the second is surely more of an interlude piece, maybe even an intro from how I envision it. so what did you think of the riffs man? you like them? thanks for the comment to!
