Harry Potter Birthday cake

I was not feeling inspired about the cake this year. I always have great ideas that I can't execute. In fact, I am debating whether or not to continue decorating cakes for birthdays, that I am always disappointed with. I need to learn how to sculpt modling chocolate. How cute would it be to put Liam's face on a little Quiddich player?
My idea here was to make the cake look like the cover of one of the movies (which Liam carries around and plays with). I don't think it quite worked though. I had to explain it to him :(
