Work In Progress

I did a painting for an animal shelter's charity auction about a month ago and a wonderful woman emailed me to ask about my art. We've been emailing back and forth and she has sent me some photos of her big yellow cat, Oscar. This is a ink-watercolor-acrylic sketch I did to show her my idea for a painting. Even though the paint is not all black and white, the purpose of the sketch was a value study, and gray scale makes it easier to study value.

I don't like the giant house plant devouring Oscar, so I plan on trimming that down a little. Any other suggestions on composition are welcome!

ps Unless you're going to recommend I take out the cow, because I love the cow!
