Both versions are very under exposed, the original more so. Was that your intent or is your computer screen not calibrated for standard brightness and contrast?

this was the first time i have ever photographed a model, so i know that i have made tons of mistakes but i need you good people to point them out. next time i will try and get the exposure right.
thanks for your help happysnapper90
