While the first thing that came to mind is a hibernating bear, my favorite hibernating creatures are toads. Just because I vividly remember watching Animal Planet as a girl and being amazed when they dug down into the snow and dirt and pulled out a sleeping frog. Amazing! Up until then I was fairly certain that bears were an anomaly, the only creatures to sleep through winter besides my brother.
I tried a different technique with the watercolors, using mostly just small circles. Overall I like the look, but I believe it needs some additional work. You can see the image I used for my inspiration.
