Colors are way too bright and saturated. None of them resemble the pitted, earthy colors of pumpkins. The colors make this warpaint look more like a nerf gun than a pumpkin.

The primary pumpkin texture has little to no detail on it that would otherwise separate it from a solid yellow-orange square. It needs more detail to, y'know, make it look like a pumpkin.

The green is way too close to lime green, and nothing like the darker green you would see on pumpkin vines/leaves (take it from me, someone who grows pumpkins in his backyard).

And what's the point of the solid orange tertiary color? It's just solid, too bright, and contributes nothing to the overall composition.

Not to mention we already have the pumpkin patched skins in game, which is where you should have looked for inspiration for not only colors, but textures. I recommend looking at some color palettes as well, because all of these colors clash way too hard with each other (much like many of your other warpaints) making it hard to look at.
