Ok this one I have an excuse for hoarding. I wanted to make sure it was long enough since the episode aired to not count as spoilers.
Rhea and riley would both love owl house so they had to cosplay. And riley needed to wear luzs grom outfit so I drew this.

Visual description: rhea the orangey skunk is dressed as amity blight in her grom dress which is mostly pinks with a sort of dark purple vest and a pink gem on the chest. She wears amity dark purple shoes and pink socks to complete the look.
Riley stands on her left (viewers right) looking towards her. Riley is dressed as luz Nocera to complete the grom fight looking scene. The puppy doesn't have shoes but has the suit top over pink tutu skirt with purple leggings. They look towards rhea. The background has the moon and purple clouds just like the owl house scene.
