Halo type figure with jetpack

I've been playing around with different styles of brick built action figures for a long time now. This would be my third type using regular minifig headgear for a closer to human scale figure.

The leg design is based on the idea that he would be able to bend his knees to be seated in some Halo vehicles eventually.

 

Here are the links to my previous figs.
