@rubio95:
i got your opinion and have to, also, respectfully disagree. (see what you did? now i have to be polite since you were being polite; you're like the trapezius limiting my neck movement. i like it better when people just say, "you're wrong! here's why:"
)
let me break down your post to try offer a countering perspective:
but the sculpt of the back of the Iron Man helmets go so far down (for maximum accuracy) that Iron Man can barely look upwards. He can tilt his head down quite a bit, because the area under the chin is completely hollowed out.
let me ask, do we post our ironman flying horizontally ala superman, or do we post him standing upright? since we know it's the latter, then looking good standing upright ie. shorter neck, should be more of a priority, than having the neck be able to tilt back and looking good flying.
Yet the mandible/cheek areas severely limit the range of \ and / movement (again, because of the accuracy of the helmet sculpt), and the trapezius armor severely limits left/right turning range. By making a small compromise, and making the neck a bit taller, this increases range of motion dramatically, with the tradeoff being that the neck is a bit too tall.
make the gap between the trapezius wider then, to make it less restrictive for the neck. wouldn't that be a much better compromise than giving it a long neck? and how far right/left do we need the fig to look anyway? look at these shots below, both are pics of the real suit(somebody correct me if i'm wrong though), not CGI:
if those are the limit of the neck's side movement for the real costume, is that limit good enough for the fig? i find it hard to believe those pics above can't be duplicated in 1/6 fig by ht, without making the neck longer.
Remember, also, that the neck, as it contains the LED bulb, must wedge as deep into the helmet sculpt as possible, so that the maximum amount of light can make its way to the eye lenses. That is why the mandible/cheek area overlaps the neck sculpt so much, restriciting movement, I think.
i dont see how making the neck shorter will have any effect on the led light reaching the eyes. the head can still be wedged into the neck just as deep, only now the head will look more wedged in between the trapezius, which is how it should be anyway.
Otherwise, believe me, most of us would complain that his head/helmet has no articulation.
restricted articulation is not the same as "no articulation". i'm from the school of thought that accuracy>articulation, so i see no problem with a fig sacrificing some articulations for the sake of the overall coolness. i know though that for most people here it's the reverse, and let me tell you, they're WRONG!
Not attacking you, and this is just my opinion.
not attacking you either, just offering my own.
Kudos to Lalla for doin' a great job re-painting this HS..it now looks more realistic! 
Right there.
