Got some ideas aswell.. in the middle of studies so don't know how much sparetime I have inbetween freelance work and homework, but.. I hope to be able to sneak in atleast one concept during these two weeks.
Eclectix, hey.. I was thinking Draconian too.. damnit
I won't go insofar as to forbid doing dragons, I love dragons as much as the next guy, and more than some. What I would like to point out is that it is not "elemental dragons", so try and see what you can do to branch out from that, thing more abstractly than existing creatures given an element. You're not just making elemental creatures, but a creature which itself represents that element. I think it's important to note that your creature, while it must have a consistent form, need not be made from stable materials like flesh and bone.
Thanks for pointing that out Si_Swe, what I had in mind regarding dragon-ish wasn't a firedragon, airdragon, waterdragon and so forth.. but rather pure flame with a head reminiscent of that of a dragon, earth in a form that reads similar to a dragons and so on.
