I love the attention to detail in this piece. The colors of his fur, the curve of his wrinkles, and even the tired look in eyes were spot on. I didn't feel the message on the sign was too humorous, but it was unexpected to see nonetheless. However, I'm sure that Tex Avery would have approved.
It's a really unique and detailed look into an iconic cartoon character and overall it's a pretty good piece. Keep up the good work!
