Sort of, but not really. I work with 3D renders, but these art I post here and there are mostly done as a hobby or occasionally paid commissions when I get them.
I like it, but it frustrates the heck out of me sometimes! :D
I have silly technical issues when it comes to doing 3D, so a lot of my time is usually spent trying to figure out what the heck went wrong instead of actually doing the render.
I'm not sure if I'd have the patience to do a graphic novel, or the story writing to come up with a good one. Definitely something I'd like to try one day, though. :)
Ah, it's a term I used to refer to the art palette challenges going around tumblr. From a number of palette sets, you use any of them with one drawing or character to draw. At each of the art I did for them, you can see a small gray/black area with the colours in that certain palette. Those are the only colours you should use for that drawing.
