A bit odd to start the new character concepts with a character I'm not even sure I'm ever going to use - she's too old to be in Aki's kindergarten class, after all. But her design was pretty easy: some resemblance to her brother, also having a somewhat sporty look to fit the family. Only those leg-stabilizer-things would use a better, less clunky look. If she ever appears, she probably won't actually be called "Mari" though - I don't like going with the masses and with the new Rebuild chara apparently having that name, it might start to fade as acronym for Toji's sister eventually anyway.

Not bad,I`ve only seen 2 other artists impressions of how this character should look,one of these was by the infamous Meguro from the Evangel site.the other artists version also had a twin pony tail hair style a bit like yours.I also like the leg braces for some reason but I`d make them more discreet tho`,all in all a good try,I hope you`ll put her in one of your stories.I look forward to your future works
