Beautiful details on the throne! Although I'm not too fond of the cut of her dress (sexualization of existing characters is not my cup of tea, but it doesn't detract from how technically well done the picture is), I really like how you emphasized it was made out of ice. You also did a spectacular job with the colors, which makes the picture convey a cold, almost callous, mood. However, amidst the spikes of ice and the storm that's forming in her hand, Elsa appears almost vulnerable. Great contrast!
Nice, but she seems to come off as more of the classic Disney "Evil Witch" here (which she could easily become, if not for Anna [matter of fact, I have read that she was originally intended to be the villain, as in the original fairy tale by Hans Christian Andersen)
Holy, epic-ally magnificent! Queen Elsa looks stunning and All of The Ice Fractals are incredible! The throne,expression, pose, dress, hair,magic, atmosphere, sunlight, textures, sharpness, concept, composition, uniqueness, colora, lighting, style, and other details are also wonderful! Amazingly beautiful work!
