Doing the drawing for Bunidoom has caused me to get a similar question a few times, so I'm just going to answer the herd as it were. Yes, there is a good chance that if you do fanart of sufficient quality, combined with post about how great my comic is, that I will respond with a drawing for you out of gratitude. The chance of this happening is greatly improved if I can see an increase in traffic to my site directly attributable to your post. I appreciate not having to whore out my work on my own. That said, there is no guarantee, but a decent drawing plus some positive publicity is valuable to me. I hope this clears things up everybody.
