Cool! Your musical ideas are inventive, good compositional choices, or at least, I liked them.
When I Fail - wow, very solid power chordage!!! Great guitar tone. I think your drums could do with less reverb, but I think reverb is one of those "season to taste" things that everyone will differ on.
Go On without Me - I liked the different rhythms playing off each other, and seemed less reverbed. I think you still might be able to pull it off with a little less reverb than you have. You might check the low "E" on your guitar, is it a shade flat?
I liked it!
cheers,
