I agree with @Econlady. It may sound new age-ish or old wives' tale-ish, but I find my icing most misbehaves when I am most anxious. Step away for a bit, take a deep breath, and look at the cookies with fresh eyes tomorrow. I assure you, the flaws you see now will be less magnified when you are calm.
I don't do counts, but I find that cratering in dots is a function of the dot size AND icing consistency (also proximity of the dots to each other). But yours are relatively far apart and big (it appears), so I would suggest thickening the icing a bit. I can get away with looser icing on smaller dots, but that same consistency tends to crater more on big dots. Also pop the cookies in the dehydrator for a minute or two as soon as the eyes are piped to ensure that they set fast and don't crater.
Regardless, given what you've shown me, I would say that the customer is not likely to be bothered by what you see.
