The manipulation is so cool. And you have focused good too. Except fot the sky I dont have any thing to complain of. Its a bit over contrasted I guess. If you can adjust the color a bit to suit the flowers maybe it will add up nicely.
Bougainvillea's are so beautiful. I like the angle of the flowers and how they naturally make a diagonal across the frame. But the dark color don't do these beautiful flowers justice.
