So after the arduous process of adjusting Leviathan's geometry so it's not royally messed up, I finally got to UV mapping (successfully) and texturing (semi-successfully) the big spirit. I say semi-successfully because I need to mess around with the shaders to figure out how to make the fin and webbing translucent and make the designs glow and maybe some other stuff. Anyway enjoy Leviathan's final design.
PS: Don't ask why the render's are fuzzy. I don't know, I was playing around with the settings on the shader and don't know what specifically caused the fuzziness. I'll have to mess around to figure that out.
