Light Blue Thunbergia???
I was not planning to add to this week's challenge again....but went to the Singapore Zoo today with guests and happened to have shot this, but did not bother to check what it was. I loaded when I got home and was happy with it. Not much post processing except bring out the structure more and sharpen up a bit. Background was dark and light was coming in overhead. I think I have discovered this flower on the internet...so if you know, please let me know if this is correct!
