Check out stuff in artist's magazines. They have all sorts of suggestions for flagging creativity. One suggestion is to do a different type of picture than what you would normally do. Taking a break might be a good thing too. I don't force myself to work on a picture when I don't feel like it. Looking at the Real world" was a good suggestion. One thing I have noticed is that I get stuck on finishing pictures and I don't devote some time to messing around. Got one cool picture, just by messing around. Was messing around with textures using Agentsmith's transparent textures and got something interesting. Nice work AlphaOmega1, that picture would make a nice wallpaper if it was bigger (1024x768).
