What's my River line after my flop raise and turn bet get called?

Villain is the loose man at the table. Likes to see flops, but will fold if he feels he's far behind. I'm tight, but have only shown down one or two hands. Folded a few flops when I completely missed them.

I don't generally raise this hand, but wanted to mix things up a bit at a fairly tight table.
