PP 100NL LAG hand with J8s

[Spellmen]

I have been reading the FAQs, NLHE Theory and Practice, and watched the JSnipes video a few times and have really been working on ramping up my aggression. I felt I played too nitty before, and have been pushing a little more to make thinner value bets and reading hands. I think I may have went a little overboard here. I didn't have a great read on villain, I had only been at the table for 30 hands or so, but he seemed to call smaller bets fairly often and fold when the money got big. I'm mainly looking for turn and river feedback, pf I think is fine. On the river I expect that he will fold a J pretty frequently, but I'm not sure if I am off
