Gerry, I don’t think the shadow is too heavy on the balloon. At first glance, it simply looks like a thick sticker. It really didn’t hit me as odd at all. You might want to play with the blur if you find it too heavy. Sometimes, it just softens it enough to look more like YOU want. The same goes for the frames; it could be tweaked if YOU want, but I would not have noticed any oddity in the shadows. It is great that you are actually analyzing those shadows. That is reflex to develop instead of blindly add shadows without thinking of it.
For the text, yes, I guess it is also a habit, and often, we start it when something like that happens and we realize it!
