Wow! That is a cake which commands respect. And I see what they meant about the chocolate curls, now - I thought they would be just random little curls all over the surface, but this is much more architectural.
I do detect a slight leaning-tower-of-Pisa effect in the third tier, but this does not detract from the overall impact, and may well be fixable anyway.
And the good news for you is that there isn't much room left for chocolate button cats to be depicted!
