Confused cake- presentation problems!

For my friend's half birthday lunch I wanted to make the most fantastic and decadent cake..... BUT.........

The sponge cake came out lovely with all the layers...
BUT.. the chocolate ganache was a holy mess!! turns out amul packs cream and milk in a tetra pack which looks the SAME!!!!
So the icing was too watery cos of the milk and I did not mange to cover the sides of the cake!

But people said they liked it! Or maybe they were being polite ;)
