Elemental Autobot Logos

By request of [link] i've created this autobot elemental picture in the same style as my decepticon one.

These are the autobot logos with forces of nature trapped with: Fire, Water, Electricity and Stone. I've left darkness/poison out this time as it didn't really fit the autobots.

Done in Photoshop, the autobot logo belongs to Transformers and Hasbro, I don't own transformers, i'm just a fan boy.
