I actually drew this on the same piece of paper that I used for the Little Drawings but decided this might work better as a separate piece of artwork (the two can be seen together here: Grenley And Ilacie). A while ago, I drew some Grenley Concepts, one of which was a gigantic and more monstrous form of Grenley based on traditional depictions of Western dragons, and I felt like drawing him again and more in full in this form along with Ilacie in this kind of state too. I've been thinking there's some kind of secret way for Grenley, Ilacie and perhaps other dragons in their universe to transform like this somehow.
