My main Spellbreaker with armour to match the Equinox weapon skins. I'm using 'lighter' heavy armor to fit with PoF maps that I'm still playing on, don't want to be wearing full heavy armour in the desert. :P
I appreciate that you didn't go the easy "Abyss + Celestial" route, and used some browns, but the Equinox weapons actually have a hint of blue to them, so mixing in some of those hues might be appropriate.
I'm not the biggest fan of the pauldrons and the violet hair, I think in this kind of look, black or white hair would be more fitting, but as @Jenpai said, there is a hint of blue in the weapons, maybe try a dark blue instead of violet ^^
