The shot is allright, very good from technical point of view (as all you shots are). But it would be obviously better without this odd flash at the right (which would also allow you to have less crop on the right, which would improve overall "geometry" of the shot IMO).
(+1 for non smoking, but I guess in our post-soviet regions this demand just won't be understood. Though you can try mentioning to Marina that smoking makes one look older, makes wrinkles, yellow teeth and fingers/fingernails, bad smell, bad breathing == low oxygen == slow thinking etc etc (-; ).
Thank you, Nick. It was a pleasure to read such a detailed comment. It's easy to remove the flash on the right, but as it looked to me, the shot lost something without that flash. Or maybe you're right. Probably it depends on the mood
I don't support smoking, I don't smoke myself and I can't argue about everything you've written (except for the slow thinking maybe). Marina told be she was going to give up smoking. But before she does, we took the chance to do some shots (-:
