First hand was played a little conservatively. I would have raised in the earlier rounds so that I could build the pot for the later rounds. Also there is the straight draw possibility which you need to guard against. I would have made it $2.50 to go on the flop. I want to know if he has JQ there or a stronger hand. On the turn you are worried about KQ but a flop raise would probably have helped remove that worry and you could safely raise him to $5 there. The 6d on the river is a great card for you. If he was just calling along the way I would consider betting the pot here or just going all-in.

Second hand again, don't give a free card. Bet .50 to try and figure out if they are drawing or if they have a hand. A draw will call here while TP may raise it. It looks like your opps. are playing passively too, though, so they probably would have just called. The Jc is a great card for you as you can now work on building the pot, knowing you probably hold the nuts.
