Sorry to bring down the intellectual level of this topic, but what are these sheets you use in scratch building? I am going to make an educated guess that it's just some variety of plastic, but what is the name specifically and where can you get it (online preferably)?
Now, comments on the progress. I just happened to notice (well it's hard not to since you only have hands up there), but are all gundam fingers the same length? Definitely not knocking your build, it looks fantastic. Very menacing. On that note I will go investigate gundam finger length now ....
