what i really like about this drawing is it uses pastel colors, giving it a softer look. Also coloring only the outter lineart black and the inner with matching colors makes it pop out so much more. The way you made the lineart in the eyes fade into a darker purple really makes them so much more noticable but at the same time it doesnt outdo the rest of the drawing but enchances it so much more. I also like how you added more contrast to the shading instead of just coloring it in a darker tone, it makes the drawing more visually appealing. I only have one minor problem and i think you can improve on it in the future. Its the ruffles on the skirt. They dont really look fluffy or soft or like ruffles per say, they look a bit like paper and poorly sown into the dress but other than that i think this drawing is very appealing in color and style.
I was going to critique on this but then upon writing it I had nothing to write about you could improve on. Everything about this is absolutely stunning. I love this style as well! I can't wait to see more art from you!
