This is a really neat tutorial! I've done inking like this often. But when I'm feeling lazy I just ink right onto my pencils and go in and erase them out before doing my details and line weights XD I find it very interesting that you do your outline first. This seems very structured and quite a good idea. I'm too impatient and I just start with one line and radiate out from there. Not always the best technique if you haven't been inking regularly for about 15 years >__> I really appreciate your attention to lineweight too. I don't see as many artists paying attention to it like this. Bravo, my friend! This is a very nice and informative tutorial :D What pens are you inking with? I usually use Microns because they're easy to get a hold of for me.

I can't remember those specific pens, but I've been using the Prismacolor inking pens since around that time as well.

This is some ace work, man. Inking is an art in and of itself. It's interesting to see how you do yours.
