Silas in Watercolor

This is my first version of my beloved cat Silas in Watercolor. The children like it. It does look like the cat. I'm not certain it look exactally like the photo, however. This took me all day. I really don't want to paint it again tomorrow. I like how it turned out. But it may not make a perfect grade for the assignment...but I'm not sure that I care.
My mother...who knows Silas...told me she thinks I need to do this again. She thinks the ears are wrong...Hmmm.
