Very nice painting, and the bases are just fine - I've always felt a base should get out of the way of the figure rather than trying to compete, myself. I've got a batch of the Pulp Figures US Navy sailors on my painting bench as we speak, actually, and they're lovely figures, although not as well proportioned as Bob's newer stuff.
Whites are a challenge, although I've come up with a couple of fairly trouble-free ways of getting good, interesting whites, thankfully!
