Shot at 25NL, how'd I do?

Villain, after playing a whopping 6 hands with him, seems to be able to fold after putting in a decent amount of his stack.

I was aiming for a flop CR. Don't see this happen too much and I thought I'd be able to figure out if I was against a set. When he checked behind on the flop I knew it was just a case of extraction and how to get the most off of him.

So, I should probably value-bet an amount on the turn that looks like a delayed continuation bet in an attempt to induce a bluff and I can stack him. My question: what's a good bet size to do that with? My gut instinct tells me $1.75 but then again I've never played at this level before.
