This is the (outdated) Boulder Class symbol from How To Train Your Dragon.

Again with another outdated class symbol. Expect two more.

I remember trying to get the body proportions right, which I found difficult. The tail was where I struggled, but I think I did okay.

This image is a bit blurry, and I'm sorry about that. The ink overlap would make anybody cringe, but oh well. It's not like I can change it lol. I used a regular brown marker for this.
