I like this picture. I don't always agree with people's skin color choices when it comes to humanized MLP character, but this fits along with my headcanon pretty well. The only thing is that I prefer a very pale Rarity because she's a white pony. That, and I think I'd prefer a short Fluttershy. I love chubby Pinkie Pie, and the implied Rarishy! ;3
Is that PinkieDash I see? I mean, Pinkie is holding her hand, so... But then again, she could just be like me and hold hands with her friend to freak them out/ be an over-affectionate freshmen. Anyways, I like. Especially that Pinkie Pie is slightly shorter then her friends, and a bit chubby.
I just noticed AJ's tan line after a few minutes of looking at the picture XD It suits her, I think, just like it suits Pinkie being on the chubby side as a human. Your picture is actually the first one I've seen where Rarity is a dark-skinned human and I have to say, she doesn't look half bad. In fact, I think I prefer her as a darker skinned human. Just like AJ and Pinkie, there's a degree of suitableness to it. And of course, she's as fashionable as always. And I just love RD's hair. If only I could find a hair dresser good enough to do it and if it would suit me, I'd probably get my hair done like that. XD And Flutter just looks adorable as always and typical Twilight to have a book or two with her. (Like I don't carry a thick book or two with me all the time. ) All in all, I think your designs are very well done and do justice to the Mane Six.
