Here is one of our cats, Sylar. We've never had a male cat before, but I totally get him and he is a great friend.
He is getting along better with our other cat, sweet little Bella. They still have their little spats, though.
This was done on recycled rough paper. I wanted to see what it would look like to add some washes with watercolor pencil. This was drawn with a Sharpie Fine pen. Next I put the watercolor pencil on , then went over it with a damp brush. I used a Sharpie white paint pen for the white part.
I couldn't find a picture of this dog where he wasn't dressed up or someone was laying on him. A very personable dog indeed!
Here I was doodling on three inch by three inch post it notes with different pens. I finally settled on a Sharpie fine pen.
This are practice. Some are fan art, some pets, and some from Facebook.
