Teenage Mutant Ninja Turtle Cake

I enjoy making birthday cakes for my friends.
This time it was TMNT and it was for my friend Roxanna.
She loved it and so did everyone else.
It wasn't too difficult to get the shape because my mom had the cake pan.
For the mouth, I just spread out brown icing and then made a tongue with pink/red icing.
Then I filled in green 'stars' for his face, then I tried to incorporate all the colors of the TMNT, but the red turned out the color of the tongue, and that's not exactly red to me.
I enjoyed making it.
