LOL!!
sometimes with the pep files , they are too detailed and i have to remove the detail because it will have to be redone anyways. most of the time i do not use a pep file. the shoulder armor i made from real thick art board then added detail and bondo. on the gaunlets i plan to use floral foam to carve a base ,make a mold and make 2 cpoies of it and make a left and a right gaunlet. if you are planning to mold your armor and stuff. all you need is the basic shape and go from there. because you will be casting the sculpts , so the wieght of the master sculpt is not important.
since this is my second helmet and armor build , it is going to be alot easier than the first, because now i have a some idea of what i am doing. on the first build it was a huge learning experience. lots of redoing things substandard molds and waste of materials. but the more you sculpt and mold and make castings the better you get at it. i could tell you all day how to do something , but until you do it. you will still have not learned what to do.
