Blue 1980s Abstract Birthday Cake

So you know how whenever I make a cake it looks like it's for an 8 year old child? This cake is for a 28 year old man. Am I getting a bit better with the age-appropriate thing?? Of course I personally would love it if someone gave me a cake with a giant kawaii cat face or hilarious little panda bear cupcakes etc etc... and I'm 32... !!My beautiful friend ShiShi requested a birthday cake for her
