I really like how different they look. Their bodies, their face, their manes, and even hooves. I really like to see a pic with two pony friends that don't look too much alike. I like their eyes, especially the blue ones. Her position is so nice too, they make her look very girly and light. I also like the spots on her hooves and ears, they're cute. The grey one looks more energtic and her style of running makes her look very determined also. I like the desing on her hooves too. It's also very nice how you made the blue one have spots only on her back hooves, it makes her look more uniuque. And I dunno why, but this pic is rather calm atmosphered in my mind, it's like these two would be running in somekind of dreamland or something... Very nice once again!
