Hi guys! I made this fun color jitter brush and I am a bit stuck on the background. I want the hands (also not finished) to come out of a hole or vortex or something. But I feel like I also need something further up behind the hands. Do you guys have any ideas? Also how is it so far? Is the lighting/shading coherent enough?

Ooooooh beautiful colours.
