Gorgeous! Really love how you draw the ponies. It's like FiM meets Gen I meets real life. That made more sense in my head. ^_^; Regardless, Apple Bloom is looking really cute. Awesome job on the shading and the mane / tail. Love it!
She's just adorable, I love the bit of a realistic approach too. She looks like a playful, slightly wobbly, young horse C: I also really love the texture in her bow, it just adds a lovely extra touch of definition.
