@72555 Taking these 2 pictures you provided as a reference- there are plenty of differences.
However they are both bit different from the actual "screen" ones (especially the phase 1...). It'd be best if you compared 2 pictures taken from the movie, otherwise it is just pointless.
Having said that- I agree with Foxbatkllr. You can argue about some little differences, but this doesn't change the fact that standard armor works fine for phase 1 and 2 with only different helmet.
