Thank you everyone for your advice, I don't think I'll have any staining problems. I piped on the black this morning and used chocolate buttercream with black americolor (so I didn't have to use as much).

The cake is all delivered and made it there without any problems. The lighting was terrible for photos, oh well.

Nicely executed. Good Job!

All that stressing for nothing! It turned out great!
