This is it. This should be your new style. I really love it. The rugged look and the outlines, gives a real artistic feeling to the piece. It looks sketchy, but not too sketchy.
Colors: Seeing as this time the main topic is Princess Luna you used only mostly blue and many, many shades of blue. I think in this work you got the color flow much more correctly than in other works. The contrast between one shade from another is not so obvious as in previous pieces. Excellent handling of neutral colors, and overall, the colors don't pop so much into the eyes and gives a relaxing and cooled off look. The only place that I don't particularly like is the background. It's good that it doesn't take away from the main object (Luna), but it's also kinda bland and boring. While I said in the picture you can't really see the color dithering, you can pretty much see it around her head in the background, which gives the piece a more low-quality look, which I particularly don't like.
Shapes: As I said before, the shapes and lines are made to have the rugged kind of look, which is not only very interesting to see with your skill, but gives the artwork a very unique look. You didn't draw any at the end of her hair though, intentionally I'd guess, but it draws my eye off to where the lines are "missing".
Light: It looks just amazing to see the blue light reflect from her mantle, really pleasant to look at. You can really see in this piece that her mane is the source of the light, which also has great texture of the night sky. The use of colors to make shading is just perfect here. Maybe could've been a bit less dithering and you could've used more shades to make it blend in more, it's still, pretty well made.
Overall, the piece gives off a relaxed mood. You clearly know the rules of composition and volume and the picture is in perfect mass balance, not falling off to either of side. I haven't yet seen a portrait of Princess Luna in such style, so I think this is a great addition to the community and art world as whole. As I said, the only thing I can complain about is the boring background and the little dithering there is (though it's much less than in any of your previous works that were shaded).
This is so good. To me, it seems very symbolic. What it symbolizes, though, I am not sure. Could it be the endless wonder that the night sky bestows upon us? The mirror of the world that some people are, these truly wise who help us realize what is right? Or is it not even a symbol? That would be fine, too. At first, when I saw this, I saw the starry atmosphere it puts out and the initial horse factor. Upon looking closer (and watching the video) I saw more. Very well done, I really like it! I'll enjoy looking at other drawings (if you can call them that) of yours!
