This is very impressive. I gotta say, I'm blown away by how beautiful this looks. Your choice of colors makes her stand out. She looks very sweet and holy. I really love seeing anime angels, and this is one of my personal favorites now. The lighting is perfect, the expression on her face is adorable, just every single thing that I find here is just amazing. It's art like this that really makes me appreciate on what people, like you can do. It's one of of those things where i look at it, and I automatically have inspiration in making an MMD model similar like this. If you can do something as vivid as this, I can't wait to see what else you can do.
Okay, so this is the first time I'm doing this so lets go. First of all, it is beautiful. The way how you blend the soft colors and how it contrasted in a way that makes this work seem so heavenly. I love the way how your tone and methods of shading give this semi-realistic feel and the balance of colors are so vibrant along with the lighting. And honestly, I think the lighting was well done, along with the shadows. Maybe you could give the wings a more soft, feathery texture? That's my opinion since the wings look really solid. I am awestruck by how define your details are, like the ruffles and the laces. The hair is painted beautifully as well, I like the idea of blending the blue tones in a cloud-shape manner. Overall, she has an image of a delicate angel, and the art work is absolutely breathtaking. Well done! ^v^ <3
