This Hardsuit was inspired by a model I discovered on Mecha Hub, a great website, even if you're not into mecha. The design was inspired by Tim Zarki's Hardsuit. Heres the link to the Bricklink Page, where you can see Tim's suit:
About this creation
In Chinese history, Sun Tzu was one of the greatest military tacticians. He wrote the book, The Art of War, which is still used today, although some doubt if Sun Tzu ever existed. The Tzu Desert Scout can change the tactics of a battle, affecting the outcome for the better. The suit is piloted by a single man, and is equipped with special supplies for desert warfare, including an external liquid cooling tank, a desert camo paint job, and a flamethrower, which, unlike an ordinary gun, won't overheat due to extreme heat.The suit is light enough that it has mounted jump jets, which allow it to burst to heights of 90 feet.
I think it would be better if you got rid of the sand green on the feet, and maybe the blue on the back. Everything else about it is good. I always had trouble building things like this, so I think you did very well.
