Pick what shape you want this design to have! Feral = Animal. Dog, fish, dragon, this is it! Humanoid = You want a person, basically. They can have ears, tails, and/or wings, but they will always look person-ish. Anthro = a mix of the two. Think Zootopia or the animate furniture from Beauty and the Beast.  

If you don't feel like this question is relevant to your design, just put down 'Artist's Choice'

Like: Winter. or Deep Sea. Or Steampunk.

If you're asking for a feralo or anthro this should be pretty obvious. Your answer can also apply to whatever the design wears. I.E. a humanoid wearing something base on a jellyfish.

Does the design absolutely have to be wearing bracelets? Or maybe there has to be some form of weapon? Oh, I know! Candy! There should be candy EVERYWHERE!

You can write something like 'Gloomy' or 'Vibrant'. You can give me links to color palettes, or even to images that have the colors you want. Or you can say 'work with reds and golds'. Up to you.

Any cliche's I should steer clear of? What about colors? Perhaps your velociraptor, under no circumstances, should have plumage? This is where you tell me what the deal breakers for this design are.
