Sorry this happened to you. The cake was very nice. Maybe you can turn it off as something to do with over the hill.
Too much moisture made the cake decorations bleed.
It could have been caused by many things: moisture condensation coming from cake if you iced it frozen, moisture from icing if it was a whipped type icing, moisture from dyed vodka mixing with fondant (makes it gummy and run sometimes). Or a combination of above.
I am careful when painting fondant to not get it too wet, or give it time to dry before applying. If you painted the fondant you tried to add lots of black too (adding more moisture) that is probably what happened.
Sorry this happened to you!
When I paint fondant, I let it dry for a couple of days. If you didn't and just painted it and put it right on, its gonna run.
