Suzan illustrations

Hello, great artists... I need some illustrations for my book, self publishing. Some of my characters are indescribable, I need actual figures drown up. I am going to have pages in the novel with illustrations of some characters. One of the characters is an alien, with coconut crab features on his head. Another character is Japanese man with a long ponytail and dragon wings, and he fights with samurai swords... Another character burns like hot coils / charcoal, and he is over 10 ft tall, a giant... It's all fantasy really, so I need help.
