You asked for suggestions about things to make in your world. After the dragon, I think a gold & exp farm would be a good addition. It is not too complicated, but probably a few new things to you - and would get your exp from nothing to level 30 in a couple of minutes.
Another idea is, maybe taking over an Ocean Monument.
