That's not actually harmony; it's doubling at the unison. But that's really one of the best ways to tighten your vocal chops and develop consistency! Do more!

YOU!

Give me pointers, I needs them. :B I attempted to put in a higher register as well as a lower register track, but they didn't quite sound right.

I BOW TO YOUR SKILLS

Oh, get up. You are worthy... you are worthy...

I wasn't familiar with "El Fusilado" so I had to Google it. I think it's definitely doable (hey, they did it!) but that chorus may be a bit ambitious for a harmony-singing novice. Since you seem to be familar with the song, you might back up to the second half of the first verse, which is just a duet.

Your voice skews a bit low (your version dropped approximately a fourth, from C to G, probably because you're afraid of being too loud in your mic), so sing along with the melody first until you're comfortable with that; then try the upper part, which might seem awkward at first but I think you can do it because I've heard your speaking voice creep into that register.

Lather, rinse, repeat!

Hmm. o.o Sounds doable, and written in speaks I can understand. Okay! :D Thanks!

It sounds decent to me! When starting to record myself I found that playing exactly in time with anything else was much harder than it appeared - when listening to yourself you're exposed to all sorts of little issues that the brain just corrects when you're actually playing it.
