COY stands for Cross Over Yuri. The premise is pretty simple, I have a list I've compiled of over 500 cute girls from various anime and manga. I then use a random number generator to make pairing, which I then draw. Every third picture is a threesome.
With this, I am officially caught up on COY here. I'm working on #14, but it could be a while still before it's up.
I kind of like this one, although in hindsight I wish I could've done something more dynamic with it. I'm getting close to being able to draw without photo references, but I'm not quite there yet. Unfortunately, that means a lot of what I do is based on what sort of reference pics I can find, and creativity is the victim. :(
