The thought process went something like this. We were all like "hey let's make a calendar, we'll do a page each" and just went off and did whatever we wanted.

By then SkepticArcher had gone and put up her Christmas image and I was like "well damn I guess it's time to pull out my Exposé and D'artiste books for inspiration" and went all detaily. A little too
detaily for some. Meh!
Now everyone shut up and marvel at how sexy Eridan is
