Transformer cake continued

Now the cake is baked and the decorations are made... time to put it all together. I strayed from my normal Wilton Buttercream Recipe to try something not as sweet. I found Julie's Less-Sweet Buttercream which sounded really good but I must say I'm not a huge fan as is. I ended up adding a lot more powdered sugar and flour to mine because the icing just wasn't stiff enough, but I will say the flavor was much, much better! I forgot to take pictures as I iced and decorated the cake but here is my finished product...

I hope everyone enjoys!!!

oh... and here's what the inside looks like once you cut into it... pretty cool, huh!?
