Ok so idk if this is gonna work but it might be cool to try to turn Kakihara from Ichi the killer into an episode edit!
Otherwise:
Yakuza themed (big ass cool tattoos and suits all the way), makeup guru, witch, lord of the rings (so many strange characters you could choose from)… I’m starting to run out of ideas hah
I think scenery helps with building up the ability to make things seem real, so it will help your overall artwork if you just go outside, sit on a hill and draw what you see. It’s really calming and you just get a feeling of content or satisfactory because what you’re doing is peaceful. I recommend going really early in the morning (like 4 or 5) its more peaceful then since the birds and wildlife are just waking up or smth so you can really hear the nature. But it’s also better to go in the mornings because (in my opinion) going at night is way to scary. And plus, you can sorta see the sun waking up and the sky yawning - you’ll get what I mean. It feels quite fresh too.
I hope this helped, you don’t have to do it of course. Maybe you’ll enjoy it.
Tell me what you think if you try it. x
