Yup, yup! I thin this happens to everyone at some point. I find it
really helps to reconnect with outside interests for a while. Just
take a break for a little while, and then come back and do what
nickedshield said. It really works. Try something abstract too.
Sometimes all you need is a fresh perspective, and Poser doodles
(take an object or figure, and play with the lighting until
something strikes you, then camera angle...or take out an old pz3
and view it from a different focal length, and focus on a different
aspect of the composition) are really good for that. >^_^
