The thing with watercolour, more than with any other medium, is that it's quite important to have a plan before you start. I say this because as a rule you need to work from light to dark.. that is, you leave the lightest areas paper-white and you add value with every strokev of paint you add. It's very difficult to take value away once it's down, so you need to plan our where the lightest areas of you painting will be before you commit brush to paper. I would use this fine sketch as the basis for a new painting where you either: i) plan the composition and placement of the various elements before you start, or ii) perhaps try it in a different medium.. gouache, acrylic or oils might be better suited to your approach to painting, as they allow you to amend / refine on the fly. Don't lose this idea though, it's a fine bear! Build on the idea; make some sketches first until you're happy with the composition and then paint many bears until you get the bear you imagined. Good luck. Can't wait to see your next bear 🐻.
