to be honest
it need alot of work, i dont know...it need more emotion, the rythym guitar is not bad but there was alot of dissonance towards the end but i guess you already know, the lead guitar needs to flow alot more than this, gotta feel the notes, try some slides and pull off maybe. On youtube there is alot of videos to explain different guitar techniques, just write in anything you'd like to learn and you'll find it.
Sorry if it seems rude but i just try to be honest.
peace.
