OK Photoport, Nice job. What I love about this photo is the simplicity of the shot. It is not over done She is only wearing a shirt but there is solo much left to the imagination. What is she thinking? Why is she on a train? Where is she?
She seems lonely. In this time of war and civil unrest any number of scenarios could be played out.
I also like the color. It is hard to get this shade to look good and natural and not to filtered. I know I have tried... Bravo.
Additionally this is just a striking photo, the background is set right. and the lighting is perfect.
Since this is a critique the only neg thing I can say is if her hair was down it would add a bit of softness.
Interesting Shot! what intrigues me is that fact that She has opened herself to endless possibilities that she is imagining through her body posture and rest. Its is impossible to tell what goes in a women mind. You can use your imagination but your prediction will be wrong 9/10 times and this picture depicts the same.
She could just be resting or being sensual or waiting for her partner or maybe even thinking about the man/women she loves, could be anything!
The edit is good, I like the color shading, however if this was a little more darker it would have a punch to the picture making a statement further.
Shutter speed was 1/100 could have been much faster to remove some grain, maybe just play with iso and shutter, there are many ways and i am sure you know how.
