Freelance this weekend

This weekend I've got a freelance project to work on, the client is a wildlife preservation group that wanted some painterly pieces done for a promo umbrella. I did mockup color roughs using Colors! for DS. For the final pieces I'm taking those roughs, polishing them up some more in Colors, and then I'll upsize them in Photoshop and add the finishing touches. It's an experiment, but one I suspect should work well.

Here's an unused color rough of a dolphin, I think I dashed this out in about 15-20 minutes:
