How did I play this hand?

[mrmazoo]

I've played one orbit and don't have any reads on villain. Do you think the turn bet was too small? I figured I was probably way ahead and didn't want villain to fold, but now that I think about it there were a lot of cards I didn't want to see on the river.

Also, what is the standard river play here with no reads?

Thanks.
