Over eager mouths are quite alright, so long as what comes out of the mouth is always something worthwhile.
I am not completely sure I understand your question though. I think you are saying your brighter pieces have too much glare, correct?
If so, here are a few tips I will recommend.
1: Don't use flash! Flash is the evilness of Lego picture taking. Instead, take a couple of lamps and light up the MOC that way. Just be sure if you use incandescent light bulbs, be sure to adjust the setting on the camera, or else the pics will be yellowed slighly.
2: When using said lamps, be sure to position them so that there isn't any glare. This may require a little while to find the right place. Or better yet, diffuse the light by having a cloth or something in front of it.
3: If you are using natural light, again make sure you are positioned so as to reduce the glare.
4: Try adjusting the brightness settings on the camera, that may help.
I feel your pain my friend. To be honest, taking pictures is the part that I utterly HATE about building MOCs. These are all the ideas i can suggest, but I am sure that the more phototellegent among us can offer more.
I build, therefore I am.
