I drew these for
Zankaru so he could use one as his DA icon. They're in two quite different styles -- the first is more realistic but in a simpler, screen-print type style and in shades of yellowish grey, the other is in pure black and white and has exaggerated features but drawn in a rougher, deeper looking style.
Both drawn by hand then scanned, I added colour to the one on the left and edited it slightly using the paintbrush tool, but otherwise they are traditionally drawn.
Other than that, other details like the eye sockets, nose, lower jaw and the shading on the temples are fine.
If you'd like, I could do a little illustration of the proportions on a real skull, I had to study this kind of anatomy for my A/S art projects (I even sculpted a skull from clay)
That's okay, I'll try making some studies of real skulls and anatomical diagrams, I've been told I should draw more from life (or death, as the case may be).
