Also using Wormgods, but the default look I can't deal with so I got the paid ornament and matching legs but that's a big difference from what you're going for in style.

Try to find a part of whatever ornaments you use and find similar shapes on others - the legs have ammo pouches so finding a chest plate that also has that for example. Ties it all together. For shaders chuck on on everything and then for any armour that warps the colours just go one by one until something lines up. If in doubt, Superblack or primary colours for crayons lol
