The brushes were created in Photoshop CC, however I have tested them in CS2 and they are backwards-compatible at least that far.
These brushes may be used in 2D and 3D art without restriction, including games. No attribution required.
This package was available early to my patrons as an Easter reward, along with other early releases and permanently exclusive content. If you find these brushes useful or interesting, consider supporting my work on Patreon.
