Wow, these are simply amazing, I'm awestruck. The Big Sister is my favorite, I can tell it was really hard to build, but totaly worth it in the end, might just give it a go!
The hardest thing i've ever built is a Halo Helmet, took me a month, hope that exp helps me.
BTW would you happen to have or know of any Mass Effect Normandy files?

Again Gratz on the amazing work!

Could you make a Palmon papercraft? It would be amazing... PLEASE! Consider it. By the way, I love all of your papercrafts *_*

Would you at all consider doing a request of doing the Unreal 3/2007 weapons?
