My avatar speaks for itself.
Are you creating those versions from your mind or are you watching footage from the movie to base your model on?
im using concept images, screencaps and toys as refference, and they are of the movie armors.
im having issues on what to go with tho ive been trying to make the mark6 but i cant find good enough refs for it to make it good so ive been fiddling with the mark3 instead as there are orthographic concet drawings of that one and they are alittle easier to follow.
i dont know which one ill go with yet.
