Ah well if I had to sort of layout my average day it'd be ~2 hours of studies and then other stuff (comics, illustration, random sketching . . ., etc.) for several hours, so not quite 50/50. Though I might spend more time on studies if there's something specific I need to work on, or spend less time on studies if I'm busy with other stuff/deadline approaching.
But there was a time in which I'd spend all day doing only studies and then another day only doing other stuff(or nothing at all . . .). Whatever works y'know~
