Honestly, considering what you had to work with, I think you did a pretty good job. You said you didn't use flash - and I see you shot at a slow shutter and a high ISO, which indicates that your lighting was poor - but I see some light there. Like in this shot:http://4.bp.blogspot.com/_VUnDX1i6dGs/S0VCr4dhZcI/AAAAAAAABrk/zyUo6RNpKgI/s1600-h/DSC_7023B_1280x850.jpgWhat was that light? Overall, I think your composition is quite good. You got some creative shots at angles, and you made an overall good shoot with unfavorable conditions. The only thing I would say is that you could stand to improve your post production because the photos look straight out of the camera for the most part. Do you have Photoshop? If so, google "photoshop actions." That should help you. I use them a lot. Kubota Action Tools is the one I use the most.
Thanks for the comment michaellacombe. I was using 2 lights, one was a 60 watt bulb, and the other one was a newer florescent bulb which was mainly pointed at the ceiling. The 60 watt was pointing at my model, the other bulb was just there to help illuminate the room.I do have PS and I appreciate the advice, I will look up photoshop actions. As far as PP goes i'm a total newbie, so I am always interested in learning new tricks.
