Could I please be surprised? Any of the lines 1-4 would be epic! Whichever one you prefer. Apart from the three colours, I'm really not bothered about any particular pattern, scales, fur, feather, etc, so feel free to have some fun with it! ^.^
Thank you so much for this awesome idea, and for what it's worth, I think you could already have your designs for sale, and people would buy them! I know I would!
Would you be up to something commission wise?
