he is mostly unknown but almost sure on the bad side

can't even think really what his turn lead hands.

Looks good to me.

What can you do better other then play it like this.
Also looks good to me

I bet half pot on flop. I'm allergic to weird/weak lines so I raise the turn almost always. As played I'm very tempted to shove river. I think villain can have lots of weak but better hands than us that fold to river shove.

It is $50 sng, gotta give credit to even a random being competent enough to not call flop bet without a pair. Villain's turn bet could be a blocking bet for a king, maybe a 7, or an inducing bet, but there is no reason to make this pot bigger. Better to pay the 150 to see if you hit one of your outs on the river, if not you can fold and still have a 25bb stack. A river shove would be very spewy.

Why are you calling the turn? You are never good there.

He picked up the flush draw.
