I like the way her tail is billowing out as though caught by a powerful wind. Except...hm, that doesn't seem to be the case for her bangs or mane. Oh, I get it. That would explain her facial expression. Beans night.
New theory: Overwhelmed by the new, sudden changes and the loss of her friends, a hundred years later (Yes, I know it was said that she won't outlive them, but I'm sticking with my first thought of her immortality) she goes mad with frustration, banishes Luna and celesta and takes over Equestria. Under her rule, it is driven to destruction.
I love the great attention and detail to the fur. I appreciate seeing things like that because they're ponies. Fur is kind of involved with them! XD Overall the picture is just beautiful and I find that my eyes keep on drifting to her wings! cx If I could favorite this more than once, I would.
Fortunately, she's guided by somepony who spends a lot of time dealing with disingenuous ponies, and who knows that Twilight is a scholar first, a hero second, and a leader of large groups only by din't of strength and logistical skill, not by inclination.
This is the most beautiful thing I've ever set as my desktop background, and is probably going to remain there as my wallpaper for quite a long time...
This is exactly how I love to see the ponies drawn/painted: realistic, but yet not looking too much like real horses, with the human features and emotions that I appreciate about their characters also evident. I really like the way you've drawn her with fur! And the amount of detail in her hair (mane+tail) and wings is also really nice...
One of the best pieces of MLP-related art I've ever seen, and one of my personal favorites. Thank you good sir for making something so awesome! TWILIGHT IS BEST PONY!!
