I expressed myself badly, the realization of the breastplate is very good with the addition of the small white line which gives relief...I evoked the illusion of the underwear with this "shorty" effect and the use of stickers 31 "the zipper". I know knowingly that the stickers on this part of the body are frustrating and singularly limit my creativity concerning me.I understand what you are saying here, but I had the exact opposite reaction to that little detail when seeing it: for me, that little white-ish strip actually helps make this probably the best version I have seen yet of the breastplate engineered from the batwing, because it added to the sense of depth, texture, and contour for the breastplate: honestly, if I didn't already know what I was looking at, I would just assume that breastplate was another equipment asset, and not an ExEq, and I think the bonemeal-white strip there is a part of that perception that is is a refined asset. And although I think there were other colors that could have been used there, because the white is neutral in a chromatic sense, I don't think it clashes too much with the darker tone of the overall design.
But, as you implied yourself, it's clearly a matter of taste more than technique, in any event. :) All that said, Glitch often uses a color palette that draws on colors other creators don't use so much: teals and low saturation yellows, oranges, blues, and violets. Undoubtedly, part of that is getting the contrast right for his sticker work and some of it presumably also his personal taste. I suspect the white in this case may be more the former than the latter. I definitely like the first version more than the second: personally, I'd love to see a gold metal work and red enamel/fabric version of this (in basically the same pattern as the bronze and teal version).
I like GLITCH for its audacity in the use of stickers and its colors which contrast with accuracy. Colors shunned by the community, give here a welcome refreshment that demonstrates all the existing potential... He handles colors wonderfully, and it's not always easy to associate them with taste. And me too, I am sensitive to this painting which embellishes it is a beautiful creation
