What piece should i study now?

[countrymath]

I have made some bach 2 part inventions, like N.8, N.13, N.4, N.2 and a few...i also have done Fur Elise and Alla Turca. The problem is that i made this pieces 6 months ago, and i didnt take any more difficult pieces until now. So, after this, what piece should i do now?

I think you should just pick a piece completely at random, which is what you're asking strangers who have no knowledge of your skills or musical interests to do.
