I liked the curves and smoothness of your shapes and the shades of color you used (and/or the filter if that's what it is?) but I think the use of hatching for light/shadows and textures doesn't fit well with it because I think it steals a bit of attention from the things I mentioned, would've appreciated other techniques for these details (like just filling the shades with dark color or drawing the minute details for textures, etc). Exceptions are the hatching with gray lines on the handcuffs and white ones on the hair, think those are subtle enough imo.
But your colors are so good. And irregularities on your lines also fit well I think, now that I payed more attention to them. And I think the background was a good choice, straighter lines and the black contrasting with your curves and the yellow/orange to create contrast and emphasis on Noelle, nice stuff.
Also, she looks cute to me and that works well with the colors and shapes, I think.
Overall good stuff, thanks for making this.
