$10 + $0.50 HU: Playing monster draws

[kitaristi0]

I'm having some trouble deciding what to do with my monster draws on the flop. Both hands below, I raised PF, and on the flop I had either an OESD and a flush draw, or an OESFD. Both times I won small pots with hands that had potential to win a huge pot. Should I just be happy and move on to the next hand, or should I check behind and try to hit my 15-outers, and possibly win bigger pots?
