25nl zoom - turn bet too small?

[renegaderob1]

Previously saw this guy raise button and carry on to showdown with mid pair with Q8o in small pot. Small sample of hands though so no real feel for his play. I think I should have put in a bit more on the turn looking at this spot. On the river I wasn't too sure whether I was looking at a set v set situation or a completed draw.
