Natural light

Hi, Lal. I think it's good that you kept the sun to her side - makes for nice highlights in her hair but in this instance it's brighter than her face so it draws attention away from it. Nice shallow DOF. If you zoom into this shot you'll see that focus is sharpest on her shirt and that her face is mostly out of focus. Focus on the eyes. That's hard to do with the mirror shades on but then the camera may focus on what the lenses are reflecting, in this case, you. You should not be seen in the photo, it's all about your subject. Also, what reflected in the lenses distracts from your subject. They can be removed and used as a prop to give you more variety. Or position her so you're out of the reflection.

Compositionally, it looks like a guardrail on the left - that can be cropped out to make composition stronger or recompose altogether.

I shot the picture below two years ago in Cancun. It's ok nd I've learned a lot since then. Believe me, I was reflected in the sunglsses but when I reviewed my shots I saw it, and I recomposed to get myself out.

Hope this helps.
