Overall the work Is solid and I could see you getting work in storyboarding pretty quickly. Your drawing skill seems professional and your design sense is good. : )
That said, the illustration style is too dominated by the caricature style and the overall site isn't really clear on what you want to do. You should limit your professional style to one or possibly two things, but to do professional illustration, caricatures, comics, storyboards, children's books, and visual development comes across as unrealistic. This can turn clients off big time, so I would suggest narrowing it down.
If you want to do illustration for a living, you may need to look at current illustration styles and lean away from the caricature style a bit. Same thing for children's books.
Overall very impressive offerings and you are off to a great start!
