Hololive Night Party [WIP] Updated (Patreon)

This time I want to challenge myself by making something more complex than before, this time the theme is Hololive's night party, for this fanart I will not make the R18 version and maybe reduce the fanservice a little.

For the characters I chose from Hololive members who have a "mommy" aura and who represent each region, namely Shishiro Botan, Moona Hoshinova, Mori Calliope, Ouro Kronii, for the one who plays the piano I have to choose one with short hair so that the back is exposed.
