We Like the looks of this cake.
I imagine it with red flowers for decoration, and maybe some bits greenery (like in the picture) and/or berries and/or candied flower petals.
I like that the tiers/layers sit right on top of each other, rather than there being open space between.
I like the four tiers, I also like three, and two. I think we should do whatever is necessary/easy/feasible/fun.
The textural quality of the frosting is not important - It could be smooth or not.
