The medication is, of course, for my bipolar disorder, so missing a dosage is not exactly a good thing, but honestly, it's not the end of the world. To be frank, I think that missing a single dose (no more than that, though) in a period of a month or so (the time since my last dosage lapse) probably has no physical effect; the drug is still going to be reasonably strong in my system. However, psychologically (even if on a subconscious level), I think it does.
I didn't exactly get much done today, at least not as much as I would've preferred, so I certainly felt the basics of that psychological effect. That said, though, I did manage to get a fair amount done. Tinkering here obviously, but I also downloaded DAZ studio and went through some rudimentary crude experiments with the program, which was nice. I also got some decent references for Davos, and began laying out a sketch on paper. Not sure if I'll make the sketch be more (I feel like I don't quite have the details of Davos's outfit nailed down in my head, which makes bringing them to picture impossible) than what it is, but I at least laid down the beginnings of it, and it did help me get a better feeling for his character.
Still, though, a ton of work to do. Visualizing his exact hair style, his exact facial expression (right now for this drawing, I'm thinking scary-mode Davos, instead of child-mode Davos, his default), his pose (got a basic idea in mind), the camera angle (I think it's basically from the front, with a slight tilt to the side), and the layers on his body (how his clothes interact with his armor--for instance, is his scarf over or under the shoulderpads, and if under, is the scarf over or under the armor itself) is all quite difficult.
I know I have it in me, but it's going to take effort to get my mind on that plane, where I have the ability to keep a consistent vision in my head and bring it 100% (rather than, say, 50%) to paper.
