Those windowboxes look delicious and the sugary snow is absolute perfection. That said, I'm not sure I could eat this construction, it's just too lovely.
Normally I'd scream overkill at a cake this busy but there is some amazing balance going on here. A striped rainbow heart inside a striped rainbow cake? A rainbow of fondant sprinkles so perfect they must have been placed there by very patient elves? I swoon for this kind of overkill.
The couple times I've gone to LA to visit, one of my favorite things to do is to drive through the Hollywood Hills in a rental car with the windows down. The views are spectacular, the breeze is lovely and how can you not feel glamorous cruising past the giant houses where movie stars live? The cake version looks like a rough drive, but munching on it would remind me of sunny vistas and gorgeous escape.
