Sorry, thought the tiefling image was from Eberron. My bad.
As far as the elf goes, is it anime to draw a character as its described? Klaus mentioned about the angular features and the like. But, elves HAVE angular features. They are specifically described as such. Is that an anime influence or just drawing what's supposed to be there?
I can't find the image, but the line drawing of the elf face portrait in the PHB shows elves to be pretty angular with huge eyes.
The Full Metal Alchemist image isn't really all that similar to the warforged image. Other than the fact that they have very similar subjects, I'm not seeing the influence. The FMA robot is huge, the WF is fairly humanoid in shape, there's no spikey bits on the WF, and the WF has all sorts of non metal bits on him.
As far as the BESM gnome goes, sorry, not going to happen. While at initial blush, I thought it might qualify, further exploration leads it to be pretty close to Hildebrant. Unless, of course, you want to start calling Hildebrant anime.
