T-Rex Cake

This was my first try at making a cake with a frozen buttercream transfer. It is actually pretty easy. Wilton.com has a very good tutorial on how to make one.
I just found out that the recipient of the cake thought the little green dots looked like peas and once that was said no one at the party wanted cake. I'm a little disappointed by this. They do look like peas but I thought the dots added some much needed color around the edge. What do you think?
