Actually I think Odie, from the Garfield comic strip series, generally says "arf," but he could say "ruff." Technically, he's thinking "ruff." He usually barks out loud. I drew this with an Odie salt or pepper shaker as a reference. I think I like Odie even more since my family and I got a puppy a few years ago.
My sister made some decorations for my birthday using a machine that makes cutouts of silhouettes. One of the things she made was of The Punisher symbol. It already looked cool, but I photoshopped it, and I think this looks cool too. I like how the skull has a metallic look to it. My sister made the cutout of The Punisher skull with a foil-like paper, which has adhesive on the back. She put that on a black paper circle. The paper is more or less like you'd use for a scrapbook. It's one of my favorite decorations she made. Below is a picture of the decoration.
Happy Earth Day! It's great that the Earth became livable eons ago and that we came into existence on it. Different people have different ideas of how we came into existence on it, but I think the important thing is that we live on a beautiful planet that has pretty much everything a human being could want or need. Earth is awesome!
