I think I made the right decision here, but any and all feedback is greatly appreciated, including any mistakes I made leading up to this situation. Thanks in advance to all the responses.

Hey, newbie and first time poster here. Thanks in advance for any and all input, as I'm not totally sure what I should be looking at in analyzing my hands. Anyway, OTH:

50NL Ignition (so we have little information on villain) 6-max.

Villain seems to be a competent player who opens on the lighter side with 2.5x, likes to 3bet, and plays quite aggressively postflop. I noted early on that he was caught firing 3 barrel bluffs when he had position. Other than a couple losses here and there, he was running over the table, showing few hands and getting value on made hands. Villain has the effective stack size of $73.

I feel like one hell of a calling station the way the hand played out. Did I overplay JJ? How could I have played the hand differently to optimize my equity in the long term? Despite villain being a LAG, the 4bet preflop sent alarm bells ringing. Villain easily has QQ+ & AdKd here, right? On the other hand, did I miss a raise?
