of the musicians I know Id say about 10-15% are quite talented in the visual art. In my case I was heavily into sculpture, & drawing and painting and these have taken a back seat when I got into playing the fiddle again. But Im starting to get back into visual art.

I also think that creative talent has less to do with left handedness or right handedness but something called field independence. In other words to be able to concentrate on a task whether it is listening to a melody or looking at a scene with the purpose of drawing it and reproducing it accurately without being thrown off by pre-conceived notions or outside influences (if that makes any sense). Pattern recognition.
