I don't think I've seen an armor combo quite like this before. I would never have guessed these pieces would work together so beautifully, but you've really made it shine!
Like Dace said, it could use some color variation, but it is also nice with how simple the colors are, allowing the armor textures to show through and make the dark colors pop. Could go either way on that one.
You're off to a great start with the screenshots-- you have a good vision for them, you just need to get more familiar with camera tools and action shots. Feel free to hit me up if you want more advice on that!
Altogether, it's a fairly common idea, but your execution of it is quite original and elegantly done. Very nice outfit.
Not meant to be taken badly. She looks nice and I appreciate the screenshot attempts but you should probably try changing up the FoV more next time, since it's still rather difficult to see your entire character properly in them.
Colours are nice and cohesive. Maybe more red in certain spots would be appropriate, or perhaps a weapon that has red on it (Bloodstone?).
