Honestly what I'm looking at here is pretty solid. you've got a nice look going in this piece. If a comic were drawn in this style I would be compelled to read it. As for Critique, that depends on where you think you need to grow.
At a glance I would say that there isn't a consistent light source (a problem I have as well). It's all very vague in that sense. You may get a more gentle/softer look and feel if you varied some of your line weights, in the hair for example. Lastly, use your lines to convey the sense of an object. Here I'm looking at the tiara/crown. It feels like it should be finely crafted, the lines for that object alone feels to chaotic.
Again looking good, just my opinions, keep at it. :3
