For me, sometimes the challenge of the final art is to capture the kind of vigorous energy of the 3 minute initial sketch. Since sketches are designed to sell the concept, they are stripped of all the finessing that takes place in the finished product. I pitched this for an article on flood insurance...dunno if it will fly, but I am already attached to the flow and ebb of lines in this drawing....and it's never a good idea to become too attached.
