I made the awesome face out of marzipan. I bought colored chunks of marzipan, but you can color them yourself.
The awesome face looks like this...
I used yellow, brown, white and red colors to make it. I didn't use any molds or templates. I rolled out the marzipan and simply cut out the pieces I needed and then placed them on top of each other. To make the brown contours, I formed some marzipan "snakes", put them around the shapes and pressed them down to make them flat.
Here's a picture showing you the steps of the assembly, if you're still lost:
The guest lol'd when they saw the cake, and then they ate it all. Nom-nom.
