Absolutely.
And I do it because I love doing it. That's the only reason.
I'm working on two drafts right now. I can barely go through a day without picking up a pencil.
I had one hosted on Drunk Duck but I got sick of the server crashing so I left. And I wasn't pleased with how I drew the early pages some I'm re-editing a lot of stuff.
Let me ask you: Have you ever had the impatience that you jump around and draw the most exciting parts when you think of them because you're so hyped up about it? ^^; I have this problem...especially with the most dramatic scenes or rabu-rabu scenes....
