Ethan's 2nd Birthday - Phineas and Ferb cake

A couple weeks ago I made a cake for my good friend, Therol's little boy Ethan's 2nd birthday.  His parents asked me to try to create a Phineas and Ferb cake and I found this one online that I wanted to replicate:

I have never worked with fondant and I will admit, I was a little nervous to do this cake first try and make it look like the amazing cake above.
My cake turned out a little different, but I loved it!  I was actually really of proud of myself!
Here's my cake:

And one of the parents at the party asked if I create cakes for birthday parties for a living and might pay me to make his son's cake! **side business!!** YES!
