I like the how clean and crisp the is, the line work and shading are very nice an consistent and go quite well together. While I don't really care much for the design philosophy of this kind of character is it is unarguably largely well executed. Her legs not being there for me is a misstep, but the manner in which you have omitted them is much better than simply having them run off of the page so good work with that. The light blue glow of the threads do a great job of offsetting the mostly muted earthy tones of both her cloths and skin, as well a create a nice direct line to guide the eye and strengthen the overall composition (which in admittedly would be much harder to pull off if you had included the legs). There are a few issues with the color fills going outside of the linework, most notably the hand on the right. The biggest issue I have with this character design is with her belt, the band on her hat her gloves and the line across her skirt and by extension I suppose all of the cosmetic stitching on her jacket as well. Right now you have two different, white-ish colors going on, for the sake of continuity in her color scheme they would definitely do better as the same color as opposed to the two. Its really nitpicky, but considering the large focus on just the character it stands out much more. Also another strange thing is the lightning bolt on her hat and the bolt earring she's wearing. I don't know your character, but she definitely has a sewing thing going on what with the thread, the dolls, and the stitching on herself, I would think, again, for the sake of character design continuity instead of a lightning bolt she should have a thimble, or a spool, or a pincushion or a bobbin or some other sewing related item, the lightning bolt is kind of random. Same goes for the bolt earring.
Either way it's a very well drawn design with excellent shading and a lot of personality. I don't personally care too much for the actual design so that brings it down a bit for me. Hope this helps in some capacity excellent work!
