He has a strange "curvature" on his back actually,maybe he really isn't supposed to walk on his hindlegs,or maybe it is just "baby fat" XD

His design though suggest that he is a biped dragon,like a anthro design or something among the lines of that,maybe when he grows the leg and tail section will adjust by themself,the future will tell. XD

I think there'll be that "no one ever ages effect" in the show; just like in many other cartoons. Sadly. :/

And I doubt they'll ever change much about him. Sadly, as well. :/

But Twilight gets taller if you look closely,maybe they will do that to the other characters aswell,personally I still hope that in the end,will it be in 5 years or two seasons,all the characters will grow,the CMC getting their CM (and they are slowly developing,which is a thing i really like)and the whole story develop into a "Good Ending",as I said earlier,only the future knows and only he will tell.
