A bit more "post transaction" advice: Take a shot of each side, and the front and rear of the model with the camera level with the model. Use a tripod if you have one. If you don't have a tripod, rest the camera on something at the same height as the model. The more of an angle you have with the camera makes it more difficult to pick up problems like which we are discussing. Good Luck!
