Space-sprayer- I did those in a sketchbook that I bought from a Super Walmart. You can buy toned paper at any art store. I can't assure you that you will find this sketchbook in any store. Materials used: Drafting pencil(it's like lead holder), Prismacolor Markers(cool greys 20, 40, 50, 80), China Marker(white), Eraser(in case you fuck up you pencils), ruler( I use it sparingly, only to check if my perspective is nearly right.) Hope that helps. It's fun process. It comes easier to me to use traditional.
Jeri- Thanx for dropping by again dude, I appreciate your support.
onikaizer- You may have to break that down for me. I am not sure which image your talking about. But, I will keep that in mind for the next multiple armed beasts I create, later on down the road. Peace.
