The DA staff used this image to promote their rebranding. Out of curiosity, did they ask you about that? If they didn't, that strikes me as unethical. Though they gave credit and technically wasn't illegal, it feels like something they should have asked, especially considering it's the cover for an RPG book.
Uhh... How the hell did I get there ? I had a strange message saying "Down of the rabbit hole". I clicked it. It said : it's coming... I waited... nothing special happened, so I clicked something to be sure (your great draw) ... ... ... and then ? Where's the rabbit hole ? Where is Morpheus ?! XD
Oh, well : as long as i'm here, I would like to say that this draw is particularly awesome ! Keep going ! And... well, uh, sorry for the random encounter, I suppose ? (^ w ^")
