I need tutorial suggestions! or votes!

So as you might have noticed, I haven't done a tutorial in a few months. Not for lack of trying, mind you, but I honestly have no idea what to do a tutorial on next, since a lot of the potential ideas, I feel, have already been done, done better, or I just use them myself already, so it'd feel very copy-paste. However I can't just 'stop' doing them, I like to teach and/or pass down knowledge, so I'd be willing to overcome that stuff and try my best anyway.

But I still don't know what, exactly to do one on. Here are some possible ideas that i'd like people's votes on, tutorials I know I can do. They don't have to be very long, some tutorials I've done in the past were only 1-2 pages. Some much longer.

Fur, drawing and shading.

Eyes, shading

Anatomy: genital placement

Anatomy/character design: Muzzles

Tips/tricks; photoshop, Clip studio Paint/Manga Studio

or if there's something in particular I've done in the past you'd like to see. Backgrounds. Glass. metal. liquids. etc. These are just some ideas, but I really want to hear from you all.
