Re: Advice on a clear coat crack
I think you need to just wait right now. Either it is moving because of an environmental change (temp., humidity), or because of a problem with the finish itself -- such as the base coat not fully drying with the clear coat over it, etc. It should eventually settle down and stop moving. Then you can decide what you want to do about repairing any cracks in the finish. If you patch it now, it will just crack again, most likely. Of course, the cracks aren't even visible in the pictures you posted, so you should probably just forget it, unless they get a lot worse.
You should find out from the artist exactly what he used for both the base coat (art work) and clear coats. If they are incompatible materials, you may not ever be able to stop the cracks. It would be pretty hard to redo the clear without losing the artwork. As long as the clear doesn't have an adhesion problem (peeling right off), it will probably eventually settle down.
