Vision: Going for a casual photograph can be difficult, as often the models pose without even realising it. It's probably my misinterpretation of the words here, but by casual, I'd like to see a model who is completely at ease, completely natural and who almost doesn't know the photograph is being taken of them. I think you've definitely captured that here! She looks so relaxed.
Originality: I hate this "originality" category, as barely anything is original these days, nonetheless, the relaxed nature of the model has scored you highly here. We're bombarded by models who are quite clearly posing, so it's refreshing to see a high quality photograph of someone who could easily not be.
Technique: There is one major thing about this photograph which bugs me. The flower at the front, which is blurred over her chest; the purple hue of it makes it stand out too much and distracts the viewer. If it had been wheat coloured (like the background) then it would certainly stand out less.
As I said though, that is my only real qualm about this piece. The focus on her eyes is gorgeous, and the contrast between her rich coloured hair, and the softer tones of the background is lovely!
Impact: Overall this is a fantastic photograph. You've managed to capture a relaxed, stunning model, in an absolutely gorgeous location.
Lovely! I like how the focal blur is focused on the model's whole body instead of just the face, that must have taken some work! I like how the horizon line in the background is defined yet obscure at the same time. The makeup choices for the model are exceptional. It makes her skin almost glow. I would have liked if there was a little bit of eye shadow, though, maybe a light purple. I also like the overlay on the bottom, how it blends with the background and blurs the edges of her dress a little bit. Great job!
This is probably my favorite piece out of all the ones I've liked so far. Not sure if it be the simplicity, the natural feel, or the sheer grace of composition. Not much more to say other than good job.
I love the color scheme in this. The purple and blue goes great with the background and it's even better that the background is blurred, focusing only on her. Her expression is great, looking off into something that we can't see. The only thing I'd suggest is to perhaps angle her body more away from us so that it looks like she doesn't notice us - if that's the effect you were going for.
The Sigma 1.4 is a great lens, but I admit my 1.2 is my favorite lens. I'd say the 24-70 2.8L is a very close second, and even the 50mm 1.2 is incredible. But shooting wide open, the dreamy bokeh the 1.2 gives is just unreal.
