I'll accept photos, but not photomanipulations unless you take all the base photos yourself. I'll update the rules to accommodate this, since I simply said "no photomanipulations." The trouble with photomanips is that it's near impossible to tell how much of the work is your own and how much is borrowed to create it.
Should we accept photos? What does a "photo" entail? *blinkblink*
Having known a photographer, I think we should open it up as an acceptable entry, since getting a good photo of an imaginary character is an artistic challenge. We'll see what happens.
Again, a reminder to all: We have references here, and we also have some 2D references (my doodles) on my dA page! Feel free to check those out too (if you need more than one reference)!
