I know it may seem like much given that you are expanding your list to include nearly all the FIM crew but, a justice league-esque wall of them together would be so frickin amazing. And I have to say i love the use of rainbow in this pic. You have managed to capture her personality and style amazingly
I must say, i love your style but the outfit just isn't doing it for me. I'm not a big fan of leotards... However, everything else is pretty awesome. I love how you choose to give her a very built body, it suits well i think.
