First, for the vision and originality I gave 3.5 stars. I feel like this isn't extremely original, but it makes up for that in epicness and impact...
Technique: I feel like this is one of your best yet and I say that because it clearly shows you are starting to develop a personal style. You are letting go of outlines for the sake of realism and it's turning out rather well.
Impact: the impact of this is rather striking. I feel like that is the strength of this piece. While it has a maybe boring portrait style centered composition it does manage to grab your attention. And that is mainly to do with the face that she is looking directly at the viewer. The colourwork and shading is also very striking.
"In place of a princess, you would have a QUEEN! NOT DARK BUT BEAUTIFUL AND TERRIBLE AS THE DAWN!! TREACHEROUS AS THE SEA!! STRONGER THAN THE FOUNDATIONS OF EQUESTRIA!! ALL SHALL LOVE ME AND DESPAIR!!"
Total foreshadowing right here. Wouldn't be surprised to see Twilight dip into dark magic in the Season 4 premier. Maybe as an added boost to handling all the stress that comes with being a princess perhaps?
This... is.. thamlies REALLY REALLY thamlies!!!! and epic, and amazing and so beautiful... i love how the eyes glow and shine out infront of everything and lights up the muzzle and the mane, it looks beautiful, you did it so perfectly. overall its more than thamlies!
I would suspect that this kind of magic would be forbidden because of how evil it is. Celestia only used it as an example, and was able to keep her composure. I love this, by the way. The light and colors almost makes this hypnotically memorizing.
Positively mesmerizing. The magic effects on her horn and eyes are particularly well done. She has that creepy and sinister stare...guessing this is the next phase of her training we might see this season?
Astounding work man. I'mma start using your work as a reference guide to improve my own stuff now.
