[oc] disco animatronics

did a little size thing because they all have different sized bodyparts!

Harley: Shortest, medium body
Bobby: 2nd Shortest, thickest body
Chelsea: Tallest, medium body
Fredia: 2nd Tallest, smallest body

the dark grey in Harley's palette is also in the others palettes, he just has one less colors in his design so i added the grey.

hopefully ill get around to making actual finished pieces and refs for them but until then, sketches and concepts it is!
