Quoting crash 703
Wow! This is really good! If you stick with this you could be building awesomely huge hardsuits that are like walking tanks. I recognize the potential in you so keep with it! And if you want to build small minifig sized ones then my advice to you is to use small parts and ones that fit together like puzzle pieces, like SNOT bricks. Hose nozzles are good to use in small hardsuits too. And T-pieces are perfect for making swiveling hips and attaching the legs to the torso.
Thanks for the tips. The only problem is that I lack many pieces like the T-piece, I only have one and my brother is using it, so I cant make any harsuits using that piece.
