Nice sketch!!

Did you know there is a second kind of barberry, common barberry, ? Your ID has been confirmed, but you might be interested in seeing the common one as well because it's pretty similar. I have only seen common barberry once, so I don't think it's a good name for it, but I'm curious if it's in more places.


Nice pictures with your hand in them. You really get a sense of scale. Good job!
