Good news folks. I popped into work earlier and did a bit of tinkering.
I think i have found an easy fix for both the mouth and the lights in the eyes(I haven't done anything about the SIZE of the eyes yet, just the problem with the uneven lighting).
Okay. For the mouth, i took a little tin of gold paint(Not a perfect match, but close enough i think), and painted the black line gold. It was the only colour of gold i had, and although everyone here will know what i have done, no-one else looking at it would know.
The original look:
With the line painted:
And with the faceplate on:
And another angle:
And at a more realistic viewing distance:
Now, on to the lighting.
Here's the problem with the lighting: With the normal eye plate on the face mask outer, and the distance from interior light to eye plate, the light doesn't reach all the way across.
See this image here(Notice how the light stops about a third from the outer edge):
My fox for this was just as easy as the paint before.
I popped the clear lens out from the faceplate.
I then took a small square of 60 grit sandpaper(The coarsest grade i have), and sanded the interior side.
It roughed up the lens.
See here, the difference:
With this done, the light is FAR more even on the eyes.
With the lens out, it would also be possible to paint a new line on the lens and reduce the area that light would flow through, so making the eyes look smaller. I don't have a problem with that though.
Here are pics of the light(Just iPhone5 images. In hand, the eyes look a LOT better, and so does the mouth):
