At first glance this is a very lovely photograph, but upon further inspection I see quite a few things that could be improved upon that would have made a better impact and feel.
First off it does appear as if she is wearing lipstick, a large amount of mascara, foundation and that her eye-brows have been defined. Also, it appears as though during the editing you air brushed her body. Also, you can see the roots of her natural hair color.
When I think "farmers daughter" I think of someone more natural looking, looking innocent and naughty.
You definitively captured the naughty part of what most people might think of when thinking of a farm girl, though I believe having the make-up lighter and her looking a little more natural would have helped to the over all feel of the photo.
Okay so first off I love this picture. It's just perfect. My only problem would have to be her lipstick (granted it's pretty on her) but its just a shade too light to go with the picture. Her skin and shirt kind of fade into the background. And her hair kind of fades as well. I see her face when i look at this picture (not her boobs, I am a woman so...boobs really aren't my style) This girl is beautiful and I think the only thing you'd really need to add is maybe a bit of a darker color of lipstick to make her lips pop out. Everything else about her is fine, but I think if the lips had popped out the picture would have been better! Overall great picture!!!!!!
