you gotta take into consideration, the visors,
where the hell will you get a visor that fits the security helmet? or the EVA for that matter
hayabusa is pretty tricky to work on
an EXTREMELY easy model to do is the halo 2 ODST, its stylish, and a monkey could pep it
first ever pep for me and it came out perfect, but, hey its up to you what you choose
if youve never had experience with pepakura, then do halo 2 odst, if you think you know what youre doing... wel, i dont know what to say, there are so many choices
