I like the model, her dress an the umbrella prop click very well. Now, the picture is a tad under exposed, the shadows are deep and lack detail. It is also too warm (to me at least) can probably be fixed in post with a WB adjustment. The POV used is not flattering to me, looking up her nostrills, you lost detail on her left eye. I would clone out the fold of her dress on her left thigh and not sure if the wrinkles on her dress across her lower torso could be cloned out (now, that is me being picky). What is she wearing on her right wrist? I would also experiment with different crops, I still find it too centered despite the umbrella being mostly on the right (picky again)
anyways, this picture looks doable in post.
care to post your set-up?
I hope this helps,
respectfully
Jim
