(sorry i know this is multiple suggestions but theyre all pretty basic so)
In terms of color schemes, perhaps:
Monochromatic
Triad
Tetradic
-Maybe a skin from a random color generator palette
Some clothing aesthetics that might be nice
-Gyaru
-Harajuku
-goth [trad, romantic, vampire, cyber, etc]
-emo [specifically scene]
-cottage core
-dark academia
Perhaps, use a generator like [
perchance.org/z8z24qaqf4] to pick a random minecraft mob and do a skin inspired by it
idk lol
Edit: ik u do steampunk primarily, so perhaps mix one of my suggestions into a steampunk way? haha ._.'
