Since Castalia is in the front cover, the back cover should be Kane (maybe I should make a wall paper and some icons with these drawings too).
I think the thing is almost done... but the more I look at him the more I think: I have to fix the jawline and the lips! XD
Anyways, I'll be traveling today and will have plenty of time to work on the train! (God bless trains with plugs *_*) Tomorrow... update!
