Tutorials? Where to start? (Patreon)

I had seen some interest in my doing some art tutorials in my previous stream when I was instructing another artist. Are there any topics you'd all like to suggest? (Do you like how I draw anatomy (eyes, heads, etc.?), painting I'll make a list of ideas from here, Patreon, FA, and all my other galleries. But the vote for what to start with, and who gets to see them will be on Patreon for 5 dollar patrons.
