My Little Pony in South Park

What would Twilight Sparkle, Applejack, Fluttershy, Rarity, Pinkie Pie and Rainbow Dash look like as South Park kids?

I came up with this "South Park" / "My Little Pony: Friendship is Magic" crossover when I decided to add some animal body parts to my website sp-studio.de. It is a tool to create characters in South Park style, you might have seen some of them around here as profile pictures. Well... The "horse update" became a "mlp update" and because I had fun drawing them I gave them an extra makeover in Photoshop. The original characters were drawn as vector images in Adobe Flash and then I added shadows and textures in Photoshop.

Now I have to admit something... I do not watch the show. I am a huge fan of South Park for over 12 years and have drawn the characters often, but I never got hooked on MLP:FIM and this is my first fan art for it. So I hope I did not make any huge mistakes with the characters.

Of course I am happy about feedback. And feel free to download the picture and use it as a wallpaper if you like it.
But please do not upload it anywhere else without linking to my website or DeviantArt account. Thanks.
