Laurenda-
I got into painting in a roundabout way. Initially, I started learning figure sculpture in wax. The results were OK, but I realized that to continue making progress, I needed to learn more artistic anatomy. So, I started doing figure drawing to learn anatomy and posing, and general-pupose drawing just to improve my "seeing" skills (I drew skeletons until I was seeing them with my eyes closed!). While visiting on holiday, I borrowed my niece's watercolors and they were a lot of fun, so I added watercolors to my sketching. I've had airbrushes for a while (model making), and it wasn't long before I started spraying washes using dilute watercolors.
Now I'm kind of hooked on painting; I'm not sure when I'll get back to sculpting (the callouses I built up have long since worn off my fingers and thumbs). My favorite sculpture style is art deco, but the watercolor style I'm working in is realistic. I also like impressionistic watercolor, though I am de-emphasizing that until I accomplish my original goal of learning more anatomy.
My favorite sculptors are the deco masters Chiparus and Erte, and the contemporary master Bruno Lucchesi. My favorite painters are the realists John Singer Sargent and J.W. Waterhouse. I like the contemporary realist masters D. Jeffry Mims and Nelson Shanks.
You're right, watercolors are finicky. When watercolor sketching, I sometimes think the difference between a watercolor beginner and an accomplished sketcher is the ability to turn accidents into oppourtunies! When I'm doing (i.e. "trying to do") realism, I work by laying down lots of thin washes. This makes any mistakes a little easier to correct. I'll try some acrylics for highlights -- gouache covers well, but it re-dissolves too easily if you have to work the area wet again.

p.s. You mentioned your husband did graphic arts for advertising. We share office space with a firm in that field. I'm a computer programmer, but I think their artists spend more time on the computer every day than I do. Computer art was just getting started when I decided (lo! these many years ago) to major in science instead of art -- how things have changed!
