A cake for a friend

Well I have a friend at work that liked my cakes, so he asked me to make one for his son. Christopher is big into Halo so he wanted a Master Chief cake. I told Kevin (his dad) that I would try but I had only made three cakes in my life so don't get your hopes up. If anyone reading this plays Halo be gentle, it was only my third cake. If you have not played Halo, and have no clue what Master Chief looks like then know this I nailed it. This cake looks exactly like him.
