Not bad for what it is.
Not bad for a drunken romp. The one thing I don't like though, is the vocals. Did you record the vocals while playing the guitar? The vocals are sparatic tonally, and they sound as if you aren't paying attetion as you sing them. The instrumentation is not bad at all, and is the best part of the piece. I particularly like the guitar bit in the chorus, but I would try putting a chordal backing behind to fill out the sound. Alone it sounds a little sparse.
I've been working on my tone with my vocal instructor. I have a very whiney tone sometimes, and we're working on getting rid of it. I'm surprised you noticed! Good ear.
And yes, the chorus is sparse. I kept trying to add stuff to it, but the guitarist said it sounded ok, so we just kept it like that.
Thanks for the review! It's always good to have these points reiterated by an unbiased individual for future reference.
