Hi Indranil. I like the wing position and eye contact. I think you had some room to push your exposure even further to the right to help bring out more detail in the lower wing. I would desaturate your reds just a little. And I would add a bit of canvas up top while removing some from the bottom of the frame.
Thanks Doug, I did realize the need to open up exposure further to the right. There is not much I can recover now. Here is updated version with desaturated red and different crop. Thanks for the feedback.
