Listen, it's a great concept for a war paint, but it REALLY needs some sort of apparent texturing for each texture. It simply looks a bit too flat at the moment.

That's just solid team colors with literal white as main texture, please try again

Like that you changed the colors but there too flat
colors in tf2 are washed and show texture
if you add that it can look a lot better

I personally like the minimalist look . but making an alternative version that is more akin to a tuxedo using this skin as base can be nice too . tho I am not fan of small details on skins. because they normally make factory new gun look like a lower grade quality .

hmm,thats not really a bad idea,i will take a look at that,i have some buttons in the works i have made,so i have try some clothe texture and add it and change it,i had the idea about colors only but this can be done too

the lime is hurting my eyes, please send help! also, its very difficult to actually see the warpaint with your current background, please use some screenshots of mercs holding the weapons in-game. also, while the color selection isnt bad, the colors just being flat without any actual texturework dont makes it look too simple and a little bit lazy. if you want it to look like a tuxedo, maybe adding buttons and seams across the weapon like its a textured cloth might give your item some extra flair that it needs.

tastefully minimalistic . I like it . though the green background is doing you disservice .
