Haha. Although you meant that as a joke, you are right

Now, I did not have that joke in mind, of course. The story behind the drawing is:
It wasn't until I was nearly finished with the top one that I decided its midsection, shoulders and hips looked more like a male dragon... and those were among the things I altered when I played around with the female dragon. I had originally intended to follow the symbolic pattern of two gender-inspecific dragons chasing each other's tails... but after the sketch started to take on more personality, I decided to make it a capture of sibling dragons instead.
On a sidenote, I have recently discovered that I forgot to interweave two other arms of the celtic knotwork into the bigger picture. So I will be posting the changes once I have time to work on that. After that is finished, I will submit the linework to my torturous CGI techniques. So keep in touch.
