I try to make my comments apropo to the image! I've noticed a couple people who seem not to get the concept between render and photo. but at least they're commenting.  One thing that gets me is that when a person faves and image and doesn't comment on the fave. I try to throw in a comment regarding the fave to let them know any additional thoughts!

As for the apology, none needed! Coffee yes! throw in a shot of brandy and it makes for a great night
