Tired most of the time, I guess. Here is a bigger version of the self-portrait above. It's a secret. If I tell you, it won't be a secret anymore, and then everyone and their mother will be as creative as I am and better. My work area is well ventilated.

I rarely draw characters that have two identical eyes. I guess I find it more intriguing, much more than drawing the same thing twice. It's definitely intentional, and I think it adds an extra measure of personality. I use to do all my comic work when I was in a state of exhaustion or at least way past my bedtime. Over the years, I discovered I didn t have to rely on that state to do my thing.
