You have some pretty decent stuff on here.
I liked your voice quite a bit, my only criticism would be your chord progression in What Matters Most was a bit generic, I thought it could've been a teensy bit more creative.
Still though, Nirvana's songs were those kind of power chord progressions, so I can't say your bad because of that.

Overall, I liked your sound, keep coming with new songs.
cool, I really like your sound. Especially what matters most, simple yet very catchy guitar progressions and riffs. I like it a lot. Your voice is really good aswell.
