can hear a good voice there, but... but...but
steve tyler (some may disagree) is an exceptional singer with an un-natural range and vocal ability for a man....i doubt anyone would be able to cover this as good as he did it, so nice one for trying
do your own tunes, and seriously, you'll be very good
if you DO wanna do this again for a proper cover, dont over-emphasise the first syllable of every word. get a pop shield on there too (or a pair of tights stretched over a metal coathanger)
back to the point (that you actually asked for lol) the sound quality is good, until the end bit when you sing the higher bits. being non-technical, i dunno what happened there, but sounded a bit dodgy.
also, sounds like you sang karaokee. pop some reverb on your vocals so that your vocal line sit in the mix more, rather than sounding like music and vocals have been thrown together to 'see what happens'.
but where you sing in your range and comfort, youre good. where you go out of it, youre not so good. practice will sort that out. i aint a good singer, but MY GOD, i listened to old demos i did before i started recording properly and i nearly fuckin cried!! they were awful!!
still. i probably still never answered your question properly did i?
cheers
