Eeyup. Rarity has entered Sonic's world of Mobius, and in turn, has become a Mobian. Mobian cat, to be specific. And I think she likes it! XD
This has been a little goal of mine; to draw the Mane Six in Sonic style, since both Ponies and Sonic are way past 20% percent cool--- *Is shot for that joke. Brushes it off.* But, uh... more on the way.
This picture took the longest amount of time compared to anything else I've ever drawn. I don't have specifics, but it took around a week and a few days. Rarity's clothes were a bit troublesome, but in the end, I think they look good!
As far as choosing a cat for the species goes, it was due to a cat's nature--elegance, grace, cleanliness, Opalescence--that I thought if any animal besides a pony, Rarity would fit a cat.
I also ran out of ideas for her tail, but despite the color scheme, I think it'll due. ^^ In any case, I really like this one.
One more thing! Pinkie Pie will be a hyper-active squirrel.
EDIT: I've noticed a few flaws in this after some helpful criticism. (Honestly, I wasn't willing to accept it at first... ^^||) The hair could have looked transitioned a little more fully, and the eyes could look a little more like Rarity's. I'mma make those changes later, probably when I get Pinkie's chipmunk form up...
Pinkie: Yeah! I mean, what's with that? You said you'd do that a long, long LOOOONG time ago, but you still haven't done it! Is this a once a year thing? Oh, know what else is once a year?? Birthday parties! OH! Do you need a party to draw mine!? That's it, isn't it!? You need a party! TIME TO PARTY!
...*Scratches neck* ...Yeah.
