wow man, it's really awsome what you did up there! congrats!
i saw you posted an image with the icons of the tools you used, but are these plugins or just tools 'cause i've been lookin' for them and i just can't find them, exept for the skin bubble...
in one of the steps you drew the different sections of the blackhawk, a succession of planes; how did you manage to convert them in the skin of the chopper?
