Now it's on to the fun job of completing the final versions. I'll just continue the cycle I've already got in motion. The first cover I'm finalizing is the Black Gryphon. I decided that I want to use the version where the gryphon is swooping down. I created a bigger document because I plan on printing all these out on 11 x 17 when I'm done. I shrank the gryphon so that more of the wings are visible. More work was done on cleaning up the edges and defining the face. The ears shrank too.
The addition of the feathers is a last minuet idea. It just came to me. I thought it would be neat to have some white feathers contrasting the complete blackness of the upper region. I added some black feathers in the lower region as well to help balance it out. The funny thing about the addition of the white feathers is that they are actually foreshadows of the end of the book when the black gryphon ends up becoming white. 
It should take one more session to finish this one up..
