I admit, I enjoy the flow of the lines, but there are things you can work on. Consistency in shading and establishing a consistent light source is very important, especially in the flat color shading(cell shading) that you do. The shading direction on the shirt and the hair are on two opposite sides, and with the hair, the shadow of the hat isn't cast onto the hair or face. While, it may be seen as destructive to put the face in shadow, it can be interesting depending on the contrast you use. The potion bottle needs shadow and looks out of place compared to the rest. The smoke could use a gradient to suggest more of a vapor. I don't know how to feel about the lining around the smoke either, I'll leave that to your own discretion. The color choice may be a little too bold overall but just remember to use different hues for shadows (usually, there are exceptions). You've been getting slowly better at anatomy, I would suggest still doing some form studies, which I have the materials if you'd like, they've been helpful to me. The connection looks weird and the head is too far off to the left making it look like she snapped her neck. A bit of a nitpick, but I feel like the cutoff at the bottom is too abrupt and harsh. A gradient disappearing into the background would be helpful. In summary, I have materials, which have helped me too with faces (and without it I wouldn't have done my Pico Day drawing), and I'm willing to show you them. You need to stay consistent , and I like the flow of lines. If you need anything, materials, more specific feedback, or techniques you can employ, feel free to ask!
