Here's my latest version. After a few more hours in front of MSpaint I decided to follow
Kclic's model which I altered extensively to suit the current colour scheme. As for all of your highlight/reflection suggestions, fear not, for they have not been ignored! It's just that I've been struggling a lot to get the helmet just right. I can't believe I spent almost all the afternoon thinkering with just a handful of pixels. and I would've spent more if it wasn't for your support. Once again, thank you all.

Now for the answers:
Being an idiot, I DID try to cram too much details in there (albeit with a larger 'face' as it seemed larger in some reference pictures I looked at).. Anyway, too much detail really:

While it's excessively big the effect is actually quite amusing; almost bobble-head like. If i was aiming for a more stylized look I would certainly do something like this.

Edit of an edit.
Try to use highlights to your advantage, Monochrome.
This just gave me a nostalgia rush. Very creative reedition, although it looks more like a robot than an armor. Those highlights are strikingly similar to style generally used by the bitmap bros on Z (Zed). Perchance you played it before? Also great work on those shadows.
*EDIT* slight update. reduced pauldron size, rearranged shoulder distance, and retouched the headplate casing.
