must fill in

they are looking neither natural nor decorated..
such a huge tree branch will never keep 3 flowers in this order..
and the colour is also gone more of yellowish..
when it comes to flower shots, i guess its better to leave it with plain sun light and ofc on the stem.

With reference to Arun's comment....

I personally feel that this shot is gorgeous regardless of whether it is "natural" or "decorated" or if "a tree branch keeps flowers in order" Despite all the faults that has been pointed out, this shot is beautiful, charming and emotive. I loved it, it spoke to me on a whole new level. As a viewer, I dont really care if it is "natural". Photography is not science or botany for that matter! All I know is this shot is immensely appealing and Manju has done a great job here. And by the way, there has no hard and fast rules for flower photography. One can and one does get fabulous shots even without sun or stems

But then, to each - his own!
