BRK,
Welcome to the forums 1st off. 2nd, you do realise that G Gundam is considered by many fans to the bastard child of Gundam right??? Well if you're a fan of G then you're a friend of mine
I lack the tallent to design such a complex design but for any who would try I have great references for it and many other G suits.
Took a pic of something to show you to. It's a production cell of the Rose I got as a Christmas present from a good buddy in Pittsburgh.
