Creat a helmet design with photos

The objective is to create an helmet design with my friends funny photos, and small expressions. The idea is to print the design you make in stickers, and then stick it in the helmet. All the elements should be envolved, creating something funny. I also want to put 2 or 3 logos in there, maybe on the sides or the back. The visor that blocks the sun must be filled with stickers or an expression. Photos of the helmet can be provided.
