ITS GONNA SUCK ALL OF YOUR BLOOD WHILE YOU SLEEP
I've picked 3 light sources (the two glowing orbs on the stem and the glowing mushroom) and my tritanopia palette to work with. I'm a little unsure about the mushroom though, and one of the eye cut-outs doesn't seem to pop out enough. I'm very fond of the stem and the orb(s) though.
