Sketching creatures is always fun. You can do almost anything and make it work because the subject matter is suppose to be unrealistic, fun and exaggerated. This is a favorite topic for me to bring into the classroom. The more outlandish the better, and it teaches the kids to use their own imagination, not just draw something they see on TV.
This sketch started from thick line thumbnail sketches to just get an idea and gesture in place. I like the inking and line work detail of the process. With a flick of the wrist and a calligraphy pen you can get an evil grin, or expressive eyebrows. The thick and thin is and randomness of the line is what I like about this style. Some of my preliminary sketches are more expressive even in rough stages. The trick is to add detail without losing the energy of the line in the early preliminary work. Keep sketching!
