It sounds good man! I was anticipating the falsetto at 1:02 and you handled it well! Also pretty good sound for an internal mic on that Apogee of yours. Do you have a band yet?
Excellent vocal performance and nice clean mic.
Mix was just ok - the pre-recorded music / backup / lead didn't blend - that's not unusual with pre-recorded stuff.
But a great example for anyone thinking of buying it.
Surprising for an internal mic really...
I like your one ear headphone technique but I'm always afraid of bleed...
