I have gone through most of your pictures and they are all very good and captivating in their different ways but this one in particular is my favorite. I don't know if its the colour which reminds me of my country's flag(green|white|green). But i will say this i love the simplicity of all the colours and how bright they all show.
Nice work and keep up the good work.
By the way, do you know the name of this breathtaking flower?
