Jumping in - Space Marine build

Hello all,

I have been reading a lot of good builds on here and thought it about time I jump in and start one myself. I have chosen the Warhammer 40k Space Marine. I do not play 40k, but I have been a table top gamer for 30 years starting with Battletech and ending with Clan Wars(Lot5R table top). I no longer play table top game, but have always loved the creative aspect of painting them, and 40k always grabbed my attention when I saw really well painted armies. So; yea...a Space Marine.

I have downloaded Pilerud's extensive Power Armor file and began, like every other newb, with the helmet. I decided to use foam and foam board. I want to use the foam board to help stiffen certain areas and the EVA foam for the bendy areas and contours. My question is do you all think the foam board is a good idea, or is there a reason more people do not use it? Here are a couple pictures of the started helmet.



I also plan to use the foam board primarily for the back pack unit. I am using the 935 scale files and am hoping that I am not wasting my time with it, because here is the kicker- I am only 5'5". The only people I have seen even attempting the Space Marine full size builds have been in the 6' range. Everyone under that, that I have seen, has used the 768 scale files.

So to sum up my questions: is foam board a good choice for armor builds and am I too vertically challenged to pull off a space marine?
