anime-style novel cover and seperate monster sketch

I need an novel cover and separate monster anatomy sketch. I already have an AI-generated mock-up of my book cover and am 80% happy with what it does, but could not get the anatomy right. I need an illustrator to polished it... (Budget: $30 - $250 AUD, Jobs: Book Artist, Caricature & Cartoons, Graphic Design, Illustration, Illustrator)
