Very nice.
From the few I saw of your other works, they seemed more anime/manga-esque (I don't know the proper term for it, I don't usually...read or watch it), where as this one seems to be more comparable to recent flashes or web-comics that've come out.
To me, your anime-type ones seems like they have the potential to carry more "detail" with them, as their design is naturally more complex. This one, however, carries with it the idea of simplicity, which isn't bad at all. Both are fine and great, and you're doing a fine job with both of them.
As for this work, I don't know what type of girl Lanette is, but judging by her expression, her haughty-little-brat appearance and the severed head in her hand, I'd think that I wouldn't want to be aaaaaanywhere near her. XD
The shading looks fine, the colors are all pastel-y looking, and overall it looks nice. To me, the head in her hand could use a little reworking; it looks a little...squished.
Overall, though, awesome job. I like both of your styles. Thumbs up. :D
