This is quite good, but even you have to admit, oil painting just doesn't lend itself to anime-styled lines.
Still, it does add a peculiar feel to it. In this case, allmost as though it were being partially vaporized.
Nitpick: I'm not sure, but I think you may have goofed on the nose-to-chin section of Nobel's Face-plate.
I'm not complaining about it though, because oil paints are hard to work with. Heck, paints in general are hard to work with.
