Huge draw turns into bluff

Game is only 6 handed atm but it has just broken up so I think posting here is more appropriate. UTG was a 29/18 player. He wasn't bad postflop but not very good either. My image is likely pretty nitty but I have been getting more aggressive in the past few hands I'd played.

Look good?

you'd do it with a set so this looks good to me. If he looks you up with tp or some equivalent label him a station and take him to valuesville everytime you make a hand here.
