Caricature is so different from watercolor, but you have obvious skill in both areas!
In my opinion, caricatures are more difficult than other methods of portrait drawing because with caricature you have to really refine the essence of your subject in a few "simple" lines, rather than the fine-tuning allowed in more traditional portraits.
Keep drawing!! I bet when you combine your watercolor with caricature, you'll make great art :-D
Yes, it sure requires a lot of practice. But it is so much fun to manipulate photos into caricatures :D
