Noise needs to be dialed back a good bit, and it would be best to have a better look at polished marble irl to do it better. It's alright as a camo, but terrible at being a marble texture.

Some constructive criticism: The colors, especially the black are way too harsh and saturated. Check out the spider season war paint for a reference. Hope this becomes a great warpaint in the future!

I can very much tell this is a first warpaint, so imma give you some tips to make others even better
1- Never use straight black/white, always try to add brushstrokes and make it more pastel-y
2-Try not to use real life textures or very detailed textures, for a example look at Dressed to Kill so you can tell what is ''too much''
3-Try to go with the tf2 color palette, with some pastely and not very over the top colors
