I kind of measure how successful a drawing is by how long you want to stare at it. If it’s hard to take your eyes away, and you feel yourself getting pulled in, and you realized you haven’t blinked for a minute and a half and your eyeballs hurt….then I’ve done a good job.
I really like these colors. Blue, purple and black is actually one of my favorite combinations. I’ve been browsing Design Seeds a lot lately looking at color palettes for inspiration, and I keep gravitating toward cool tones. Maybe to mix it up, I’ll use colors I absolutely hate next time. Pick some jarring, obnoxious, nasty combination. It could be interesting to see what happens.
