Here are a few illustrations I've been working on, two whimsical, one more of a caricature:
This one is going to be called "Underwater Rumble" and the octopus will be holding a deadly weapon in each of his tentacles. In the immediate foreground will be a diver's right leg and right hand dropping a small dagger. I've had this idea for ages and have done a few comic iterations; this will be the first painted edition.
The Angler Fishbowl; I thought it's be funny to see an Angler fish in a fishbowl at night while all the moths are attracted to his natural bioluminescence.
