trained on around 160 images from diabolik lovers! at least ten of each boy, trying to keep it varied :)
couple things:
ability to do individual characters isn't great, given it tends to fuse traits between them (i.e. reiji looks younger like the other brothers) so it's better to use character models if they're accessible
if you don't put any bg details it'll just be a neutral gradient
experimentation is your best friend :)
