Start looking at photography, start looking at art, start looking somewhere other than Maxim. A great place to start is with the other stories in this issue of 180. Look at how these artists have interpreted "glamour". You've got lots of shots of models looking sexy and pouty now, so try something different.
Mix it up and blast away:
As one fellow photographer says of my shooting style, "even a blind monkey can get a good shot once in a while". Get a fan, show the studio, do anything to break up your old habits. It's digital, you've paid for the camera, the shots aren't costing you a dime so shoot shoot shoot. Kick the lights around and see what happens. While it's not likely that you're going to come up with a new way of lighting a pretty girl, you may come up with a way that's new to you.
