I outright LOVE your art, the Mane 6 and Luna especially but this is so far my all time favorite.
Your pony art style is unique which is what originally caught my attention and within every deviation your styling improves, the reason why I love this one so much is because of the coloring of everything, allot of people use brighter shades of her colors, unless of course it is in a dark setting. The colors you used however are between those two marks, and personally I like it.
I also lover her expression shes like "Hey.....see this....this flower...yeah you know what that is, come on over here"
Lol Please keep the art coming its a wonderful surprise each time you post.
