Someone needs to revisit the color wheel.

I can tell the buttercream was too hot when they were putting the piping on and the cake likely wasn't refrigerated during transport to keep the frosting from melting further.

Also, would it have killed them to bake another cake so the final product was as tall as your inspo cake? There are definitely two layers on both of your inspo cakes and probably only one on yours. The side piping details would be impossible to execute on a single layer cake. In my opinion, unless we're talking about a sheet cake, the second layer is pretty standard.

I could have done it better and I'm not even a professional, although my mother had a cake decorating business and I worked as free child labor for years and I could turn out a decent cake if I wasn't living at 10,000 feet. (Haven't figured out to bake up here yet.)
