Thanks so much again for the kind comments guys!
Um... ok, I've never heard of "bejedi.com," so I hope there's some sort of sarcasm played in here... I really try and strive for originality in my designs, you know? Nexu were actually quite popular as pets and came in many color varieties, seen in a few comics here and there (including a smaller nexu in the arms of San Hill in the "Visionaries" Graphic Novel). I don't think really anyone has the right to "claim" to the idea of it. But hey, great minds think alike hmm?
Actually no, haha. I've had no art schooling and take pride in the fact that I'm self taught, though I'd really love to persue a fashion/design major, that is if it'd be designing armor and the like and not some silly dress on a runway. 
I adore designing mando'ade, so for a small fee I'd love to be able to design more armor scemes for people who'd perhaps be interested. I'd love to do it for free, but art is my source of income and that of which I need to work on this project.
Yeah, certainly. I'd go for taking a live cast of the actual person with plaster bandages, then re-enforce that mold and then go for a vac form.
Another idea might be to look up some torso modeling Mannequins(the ones you see modeling lady's undergarments), build them over a little with some sort of heat resistant modeling material (perhaps air drying paper clay sanded down?) to make them look a little more rounded, thick, and give alowance for the material warn under the armor. I searched all over ebay myself and the prices average at around $40 I believe. Sadly for myself I couldn't seem to find any that would suit me.
Anything to avoid the awkward "bubbles" that I believe would come forth from a freestyle attempt with flat sintra.
Hope this helped.
