The strongest part about this manipulation is that you have certainly conveyed the idea of "cold". Looking at this piece just gives me the chills. The coloration of the background and the model truly makes this look like a winter scene. The snow wasn't overdone, either.
The blending is fantastic; the background looks to be a very cohesive whole rather than being separate images put together. Everything just fits.
There are just a couple of suggestions that I have. The first is to have the model cast more of a shadow. Since the light is so strong behind her, the ground should be darker in front of her. I can see the reflection of her figure in the water, but the reflection actually brightens the ground right at her feet. It would be best to brighten the sand on either side of that reflection and darken the area the reflection covers.
The second suggestion is to lower the brightness level of the sky - not by much, but just a bit. It looks a little overexposed. As a result, it's a little distracting. My eyes were drawn to the sky first instead of the model and the foreground.
I hope this has helped you in any way. This is a beautiful work, and these suggestions are minor. You have done a great job.
O_O it does look very cold, especially since the girl has blueish tint to her already pale skin making it look frozen *shiver* that would suck. ANYWAY this is awesome, i love the girl she's very pretty, and the whole photo in general is really beautiful! Great job! :]
I like the use of the blue hued colors. The expression on the girl's face evokes the 'lonely' feeling rather than the 'this is an ice princess' feel. Also, the bits of falling snow are a nice touch. Even though I wouldn't use it, I sort of like the umbrella. If I were you, I would try another picture without the umbrella but the same cold theme. Or, if you wanted to keep the umbrella, maybe change the outfit she's wearing. Overall rating: I like it a lot. You have a great sense of style and a unique artistic touch. Keep up the good work. : ]
