What piece of music should I learn next on piano?

I’m learning piano by myself, it has for half a year, and I just finished learning Shrek Fairytale and now I do not know what to learn next. Does anyone have any suggestions? Here are the songs that I know how to play (organized by time to learn): GreensleevesA a Wild RoseUna villancicosHallelujah many BuckleyTema Jeff Simpson (http://www. Youtube. Com / watch?
