In this work, 50 brushes of "alien" are provided, each with a separate setting. The main idea is inspired by @H.R.Giger which is based on both "Organic" and "Industrial" textures, so you can use these brushes for the details of artworks like "creatures" and "Zombies".
Besides, these brushes are in the form of "Roll" and "Tiles", and they don't overlap with each other so they effectively boost your work speed!
If you purchase this product, in addition to brushes, you would have the tileable textures (AO, DI, Normal, Cavity) with 2k and 4k alphas.
