For the last two weeks I've been putting together the first e-workbook for my workshop series, Nature Sketching Basics, and I pretty much finished it yesterday, in PDF form. I'm letting it rest for a few days before I put it up online, so that I can check it again with slightly fresher eyes.
My question isn't about that one, though. It's about the second ebook in the series, Nature Sketching Details, which I'm now working on.
Here's my dilemma. When I give my workshops,

So I've been photographing shells and leaves and other goodies to give them something to draw if they don't have the suggested items on hand. I had plenty of stuff to photograph for the first e-workbook, but now that I'm working on the second, there's something I'd like to add.

Maybe I'm being too cautious, but I don't want to put anyone off, and I don't know if animal skulls are in that category. I personally think they're great drawing subjects. Could I get your opinion?
You don't have to say much, just whether or not you'd be caught
