Alien Races Design

I'd like to have an "Alien Race" toolbox. So, I have 4 "categories" (or groups) of words, which describe an alien life form. There's the "Base group": - Rodent - Frog - Lizard - Lobster - Bird - Humanoid - Feline - Insect which says, which race an alien is. Then there's the "Appearance group": - Slimy - Bug-Eyed - Horned - Bony - Fat - Furry - Mutant - Weird which describes the general appearance of the Alien (with "weird" meaning that the Alien could belong to a mental institution :)). There are two more groups, called "color": - - Green - Red - Yellow - Blue - White - Harmless and "size": - - Large - Small - Fierce What I like to have done, is to prepare the "Base" look with all "Appearance" types -- in itself yielding 64 images (Slimy Rodent, Bug-Eyed Rodent, ..., Slimy Frog, Bug-Eyed Frog...)! Use one color-style for all these images (either Green, Red, Yellow or Blue -- please don't use white). (Obviously you can use other colors as well, but the base skin color of these aliens should be greenish/reddish/yellowish/bluish). If you choose one color for your first image, you have to stick to that color for all others. More details on the subtypes: - Slimy: I see this one literally as covered in slime, a gluey substance dripping from their skin, should be a natural for frogs - Bug-Eyed: Google images for "bug eyes" and you see what I mean: Big convex (or concave? I always mix them up) eyes filles with hexagons. So, here you can reuse the complete frog and "only" modify the eyes. - Horned: Adding horns suffices completely - Bony: Bones showing through -- that could be a more complex task; but still, you can retain the base structure and "just" add some bony structures. - Fat: Well --- heavy... - Furry: Attach fur (of any color that you like; doesn't have to be in its own layer, just let me -- still! -- change the underlying skin color if the skin shines through in some places). - Mutant: Here, you can maybe combine different heads of aliens (or bodies), maybe you can also reuse images here, by attaching the legs of a lobster to a frog, or similar... - Weird: I always see "weird" as a lunatic. Maybe cross-eyed with saliva dropping from his (skewed) mouth, giggling like a mad-man?! Something like that...
