Minecraft head generator

I posted a project on Tynker related on Minecraft. This project lets you generate commands, that when you type them in, gives you a head with its custom skull owner to use as a decoration or put them on. The project is at https://www.tynker.com/play?p=5978f44876f293fd208b456e. I am new so i do not know exactly where to post this, but dp you have any suggestions for this project?
