My first realism tag, I need C&C ;p stock used: http://pix.alaporte.net/pub/d/13013-1/Dark+Hallway.JPG
I think the position of the stock doesn't look right, if it was more centered it think it would look better. Good try for a first though.
she definitely looks out of place compared to the stock. shes lit up when the bg makes it look like she should be dark i would try a brighter background with that render
nice concept,but it would look better if you shift the render to the left just a little bit,and adjust your lighting to match.still,not bad for a first attempt
