I love Luna, and I love the creative way she's portrayed here. It's new and original and cute, and I think it's awesome! Her accessories, wings and cutie mark are perfect, and I love the intensity and depth of color. Her mane and tail are some of the best features of the entire picture. The gradient is beautiful and blends in with the rest of the background really well. I think this image could even be used for a desktop background The problems I notice are few and not too important. Her neck seems to be a little thick, and her ears and eyes are very large. I think if you toned down the eyes and ears a bit, you might find a more elegant pony. Still I love the chibi look, I just don't think it fits in well here Beautiful job on my favorite pony!
