I don't think we can really advise you on 'what to do next'. At least you've listed a few songs you've played so we have some idea of the type of music you like, but we don't know what style of guitar playing you aspire to. Are there any players you admire and would like to be able to play like? If we knew that, it would be a better point to start from.

My advice would be to go out and see as many good players as you can, or go to sessions and watch how others play, and if you see any you like, watch how they play, and if possible ask them how they do certain things. Most musos are friendly and would be happy to help.
