This was a fun experiment. Synthwave Slaanesh
Steps:
1) black prime with white drybrush
2) light blue airbrush from top
3) fluorescent purple airbrush from bottom
4) 2nd light blue airbrush from top because I overdid the purple
5) covered the entire mini with a purple contrast to add definition, but I think it ruined the gradient and has to rework via drybrush
6) selectively added white to the tops and under surfaces
7) added more blue and purple to punch up the saturation
