Thanks for the class! It was great, and I discovered new techniques.
In this illustration, I played with a drop of ink on very wet paper, for the body, which is a technique I often use. Then I let it dry, and added the head and legs with a pen and nib (I rarely use a nib, it's really fun, I wanna use it more now). And then I added the ground with a dry brush and diluted ink. It's the first time I use this technique and I really like the result.
