Great shot! To nit-pick your histogram reveals some blown-out highlights. I dropped the curve slightly and added local darkening of the cement wall ( a tad bright and distracting) to bring it under control and focus all attention on the model. What do you think?

I agree with the above however IMO you are disregarding wonderful elements via under-exposure or perhaps under-presentation. There are nice details ( bed sheet, floor etc) that are easily revealed by brightening shadow areas without adding noise or altering the mood. I'd be curious to see what you think of this:

Beautiful! My preference would be to tone the sky down. I tried a grad neutral density filter here:

Hi Gatis, nice shot. Because the lattice is so large and prominent in the photo, I'd apply leveling and crop in something like this: What do you think?

Hey Bobby, I wanted to pull out more grit, saturate colors and darken the upper corner to add some drama. What do you think?

Hi Nima, a pleasing shot. My suggestion would be to shoot from a higher vantage point OR move closer. She is consumed by ( appears seated too low in) the boat. You can change the perspective somewhat by cropping off some foreground and allowing your model to fill more frame something like this:

Nice shot....yes IMO a crop could improve the image. Additionally I added a silver reflector effect originating from the right-hand side. This justifies the harder wall shadows. Reasons for crop might be wrinkled sheet and awkward left hand are minor distractions. Tonality and expression are perfect. Well done.

Hi Gabriel, I know this is contrary to your title IMO your shot of interest is here:

Nice! Why not take the final step and eliminate blemishes and soften like this:

Great shot. How do you feel about this? I find the elbow joint very distracting.....do you think it can be de-emphasized somehow. I tried blur here:

Hi Kelly, I played with the crop, tonality and lighting just a bit. IMO this gives a static image alittle more interest and drama. Do you like the re-worked version?
