After being challenge to create my own specifications to work within, here are my thoughts and choices (I made up my own, so these may be worded funny):
warm or cool colors = warm
rough or smooth = rough
cute or grim = cute
Soft or hard = soft
more colors or less = more (8 color ramp)
modern or vintage = vintage
After deciding the categories, my selections were decided via coin flip. Oddly enough, every result except the last was “heads”. I’m not much of an artist yet but I’m looking forward to being able to draw my own assets for my games, so we’ll see where this goes!
