Two Pairs Not Good Enough

After the flop on this hand i was facing two opponents who were pretty much limping every hand and rarely raising... i had pushed them both off pots several hands before with continuation bets... when i was flat called and min-raised, i thought that catscan was making a weak attempt at pushing me off a pot due to the fact that i had raised nearly every flop I've seen... that coupled with the pot odds (nearly 6 to 1) and the fact that i believed i could push catscan off the pot on the turn... i called...

When the queen flopped i knew i had the best hand and i wanted to bet enough to get called but also not give the correct odds to call for a flush draw... my bet size is ok i believe, if i had of made it bigger catscan would have called anyway (he had called me to the river with a middle pair in a previous hand so i believe he isn't a very solid player)...

When the Ah hits i believe its a good card because catscan has played many rag Aces further than he should before... two pair was an option i thought about but the pot was too big for me to make a lay down like this... when i saw the flush i thought i should have bet more on the turn... its a marginal choice but i should have given him less respect and bet more i believe...

If anyone can see any glaring mistakes i made during this hand please let me know... I'm always open to constructive criticism...
