I hope that this helps, I`m not a professional at drawing eyes though. It was just so hard to find any tutorials for blind eyes from deviantART, so I decided to make one by myself. This works at least for Paint tool SAI!
Yeah. I watched a video last night about marker vs. colored pencil by Mark Crilley; he has a set of colored pencils. (Prismacolor) and I guess i just need more shades. The only thing ive been doing is just not drawing a pupil. :/ Thanks anyway, though! ^.^
