Marceline the Vampire Queen

New Style Alert! After my commissions journal, I was well-funded enough to get my much sought-after tablet, and this is the first work I've done completely using it and no paper. Of course it had to be my girl Marcy. I'm loving it, and while I haven't come close to mastering it and I'm still not completely used to it, I love the sketchy quality of it and how I can go into greater detail on faces, hair, and clothes.

It takes far longer than the usual pic so I don't know about doing everything, like comics, like this. But I will do my pinups like this when I wanna make it special, and I'm adding this to my commissions menu for $20. Call it a....Super Pinup?

PS. I currently use GIMP and I'm super used to it, but I recently downloaded PaintToolSai, which I've heard about constantly. Anyone know about the pros and cons between the two? It'd help before I choose to switch
