Okay. re-hello. when I arrived on the forum, I found this page of advices for a beginner: http://www.thedentedhelmet.com/showthread.php?t=13569. Pick an eye, it's full of informations for a beginner. But I suggest you to take your time, don't rush into the realisation until the design phase is not complete. you risk to spent a lot of money, and will have a bad-looking armor.
I heard that you want to recreate the Awarru Tark armor? he's the one who wanted to kill Lord vader, isn't he? but I can't remember his armor. could you post a pic of his armor, it will be easier for everyone to help you.
