Hand for review

In this hand I tried to think about possible ranges and also bet sizing.
I don't have any reads on the villain but he was playing the usually kind of thing for 2NL which means any pair, and any single broadway card.
$0.01/$0.02 No Limit Hold'em - 9 players


UTG+1: $1.49
UTG+2: $2.91
MP1: $2.18
MP2: $1.21
Hero (CO): $1.89
BTN: $0.94
SB: $2.72
BB: $1.34
UTG: $3.31

Pre Flop: ($0.03) Hero is CO with Q A
4 folds, MP2 raises to $0.07, Hero raises to $0.12, BTN calls $0.12, 1 fold, BB calls $0.10, MP2 calls $0.05

I raised him because I am trying to get out of the habit of limping in CO or button with hands like this. If I'm going to play it then I'll raise it.

Flop: ($0.49) K T A (4 players)
BB checks, MP2 checks, Hero bets $0.24, BTN folds, BB calls $0.24, MP2 folds

I hit with the flop and I'm thinking if either of them had AA or KK preflop they would bet something here so I make a c-bet. Also I now have a straight draw. If either of them had hit their straight then they would raise.

Turn: ($0.97) 3 (2 players)
BB checks, Hero bets $0.48, BB raises to $0.98, Hero calls $0.50

Now I'm not sure. Maybe he has Kx or Qx and he thinks I am bluffing. I have pot odds (I think) because I still have a straight draw and the chance of getting another pair or trips.

River: ($2.93) 5 (2 players)

I didn't get anything out that so I checked and so did he.

What are the things I should be noticing?
