Some quick head studies I did when I was on EF.
After Wolfy pointed out that people only drew him facing sideways for me because my badge was the only reference I had, it occured to me that I never really have drawn him from any other perspective myself.

I think these came out okay-ish, but I'll make better references sometimes when I modelled a little plastiline head of him to give myself a better idea about his head anatomy.

Those teeth are also not canon (anymore); they're obviously carnivorus, but Pranko (and his entire species) is omnivore, so my icon is a more accurate portrayal of the teeth in that regard.
More on them another time.
