Under The Sea, Under The Sea, Under The Seeeaaaa!

Here's a picture I put off completing for quite some time. Tried using a new homemade shading tool, which I learned how to make from some book I bought. So yeah.. First I've tried drawing an underwater scene thing since my interest in drawing picked up.




Yeah. Considering taking art classes for fun, joy, happiness, giggles and everything in between.
So yeah.. Any comments/criticism/compliments/credit card numbers you'd like to give me?
