It's a good start. The vocals are pitchy--and to some extent that adds to the effect--but maybe a bit too much. It sounds like you have an A part and a B part, but need a chorus. Not crazy about that guitar sound. It's interesting at first but wears fast. There's something about the attack of the notes that sounds like you're clipping the input. Maybe it's an effect, I don't know. It also sounds like an amp sim. No need to worry too much about the vocal recording until you've got the song finished, but when you do get around to tracking the for-real take, consider your environment. I'm hearing your room in the vocal, which the reverb seems to bring out more.
