I think this a really good pice of art. At first because the character is really cute, in your style she is even more! The way you color is really unique, I never saw someone who made the shaddows like this. Because o that her clothes looks more 3D, I think. The calm colors make it easy to look at it and also a pleasure to look at it. I think it calms yourself while watching down. However, there is one thing I have to say isn´t that good in this drawing. I think you could have drawn her in another, more dynamic pose. Here she is just standing. But that doesn´t mean it´s bad :3 So in the end I can say this is a really awesome, no, stunning picture with a lof of details.
I say, really great work, thanks for making my eyes smile, hahaha :'3 have a nice day, Ioko~
I like how this character stands out more from her background, but I think you could lighten and desaturate it just a little so she stands out more. Her pose and anatomy are quite nice though like someone else had stated it could be a tad more dynamic.
For her dress, I think you could add just a little blue to it, as it looks almost pure black. I don't know if you used lighter and darker versions of the base colour for the highlights and shadows, but it does have that effect somewhat. Her hair, from a distance, looks like you just used plain gray to shade it, but it does have a more French gray look to it so it does look pretty nice. One thing I do have to say about the way you coloured her dress and all the laces - they do make the blue ribbons and rose stand out very well.
I also like the little coloured specks and dots on her dress, as they give it some personality.
Her facial expression could use a little work, but I like their eyes as they match her ribbons, and the limited pallet works so well with this picture.
Very pretty picture, and the background isn't quite as overpowering as it is in some of your pictures. Sometimes, less is more.
