The Lethiferous Moose

Hello everyone, I'm new to this forum and am seeking help to complete my scout trooper armor. Do there exist any detailed tutorials for adding the movie accurate details to the armor (painting, backpack add-ons, thermal detonator parts, etc)? Also I've been stuck with an inaccurate Rubies helmet for some time that I would like to try to modify rather than buy a whole new one. Any help/instructions there would also be most appreciated. Thank You.
