This is quite a brilliant piece that you have crafted here! I love the way that you crafted the atmosphere to accent the essence of Twilight! The wonderful color work is amazing with it's changing shades and hues of that deep purple! The soft textures contrast extremely well with the solid line work and the character design flows beautifully with the minute details such as the grass, her mane, and tail! Every element of this piece comes together in such a lovely way! This is a fantastic piece and I would really love to see more in the near future! Great work! Kind regards, Princess Luna
Well, fancy that. I drew something somewhat similar (in terms of composition) quite a while ago. However, this work is infinitely better than mine (emphasis on "infinitely", because there really wasn't a better word) Here's the link to my drawing (to give some credibility to this entire comment): abronyartist.deviantart.com/ar…
Clearly, the strongest aspect of this piece is the use of color. Astounding use of colors in the sky, with so many different shades blending and mixing, and the greatly varying brightness, slowly fading to black towards the edges to direct attention to the center. These all serve to give a feel of magic and mysticism to the night sky, as well as a sense of awe and wonder.
Twilight is also very well done. You've spent a lot of time working on the mane and tail, and it clearly shows. Even better in my opinion is the attention to the body - I like how the shoulder blades are slightly highlighted, as well as the curve of her spline. The lighting everywhere on her is done well. Also, the brighter lighting on her head and ears help transition from pony to sky, as well as serving as a focal point of the image.
Probably more impressive than any of this is the originality of the pose and the thought behind it. Very few people would have thought of drawing a pony facing away from the viewer, even fewer could pull it off without losing the interest of the viewer. But you have done an excellent job with this. Thank you for this wonderful work!
