These are personal, slight modifications to the official Eclair/ Lightning forme, just for the sake of having fun.
I made this a very simple coloring and shading.Alternate colors here: [link]
A> Is obviously closer to the official, although hands, feet, and most of the face where retouched.
B> Places the tail again, and connects the previous "tail-head" as a thicker tube to his back.
C> Removes the "tail-head" completely, but leaves the aileron.
After thinking it more carefully, I finally went with the "young" aspect of the official version. The reason is simple:
When the producers say "Mewtwo's awakening", they're most probably pointing out, that the Eclair forme is not only a speedier forme of Mewtwo, but also,him becoming closer to his true origins: Closer to Mew. (Not a 100% closer,of course)
This would probably serve as a mayor plot device in the movies, and/or the games.
I really liked that idea of him, getting closer to a more "perfect" clone, so I desisted of an adult Eclair.
(Plus, being smaller obviously makes him lighter,thus probably faster. Just like I did with my own "Speed Forme")
Also, I replaced the "horns" for something closer to Mew's ears,but staying aerodynamic at the same time.
And last, but not least, his skin here is slightly more in-between pink and violet, instead of plain white.
You know, this skin color thing makes me wonder:
We all know that Mew was cloned from an ancient Mew's fossilized hair.
But, what if you would make a clone of Mew, out of a fresh hair fragment,recently plucked out?
Could this explain Mewtwo's overall physical appearance? Would he look less "anemic" maybe? Perhaps overall Pinkier?
I dunno, that was me thinking in a loud voice
Next: Mew's Eclair forme.
