Hello, ZenoWai09.
Allow me to share with you several points.
Exposure
- good. Nothing to criticize on.
Framing/Composition
Abhaya mudra - the hand sign of
protection.
I think what you are trying to do is to portray this powerful gesture and to convey this feeling to the viewers.
It is good to have some green background to the right side of the Buddha. But limit that, otherwise it becomes more of a distraction.
I would suggest leaving only a small slither of the green background on the left.
The rest of the Buddha's body serves also as distraction. I would suggest cropping out until the hand occupies the top half, and left half of the frame.
By doing so, the viewer's attention would certainly be drawn just to the hand.
Further
I added this in as an afterthought, as I kept thinking about how to make this shot better.
It dawns upon me that one reason is also because it looks a little too flat as you have shot it full frontal view.
May I suggest going at it from an oblique angle. Use a slightly wider aperture and take the hand at an angle from the side so that the background becomes out of focussed.
This would isolate your subject (here, the hand) from the background much more effectively, and the angle would give it more depth.
As usual, these are but my humble opinion.
Keep practising and keep your photos coming!
