I had whole hour and a half free time between tensile strength tests and lectures so I went to school library to spend time, read science magazine and drew this. Includes some perspective caused flaws.
I'm a such pleased, I didn't have any skeleton refs, though, so maybe should re-draw this someday... Anyway, creating skeletons is fun, I've seen some good (and bad) pokémon skeleton attempts around.
I think its tail (and mane) is mainly some etheric fur, so not much tail itself. Accessories, collars and tail torch (which actually seems to be some kind of oven, with heating elements and heat conductive cone shell*) are another story.
Wannabe-professional looking pencil thingy.
* I repeat, I study ENGINEERING SCIENCE so, yes, I've created a valid explanation how the tail of this monster works....and should explain it someday. Besides ether is very easily flammable, thus etheric fur was necessary. ... Regardless of this don't ask how fire doesn't cause any visible damages to Reshiram self. There is some dim Pokémon logic where real life science can curl up and die.
