I had a nice warm bath yesterday, and afterwards, thta was it for me as far as drawing went.
I'd been drawing stuff (mostly) on my laptop using the graphics pad and either Art Weaver or Paint Tool SAI in the lounge room, and the laptop/tablet combo works really well with either of these applications. Butafter the bath I took a shot at inking Trope World -- which I'd pencilled last weekend -- in Illustrator and got a bit lost and a lot frustrated.
I know when to quit, because there's always more I can do the day after. However, I go no webcomic pages done at all yesterday, even though I did get six drawings done. Today should be a housework day. I will cut vacuuming the floors and not mow the lawn, and fit in some art work after the rest is is done. Even if I don't get a lot done today, I will stick at it tomorrow.
