To boldly go where no brush has been before , joking aside these brushes are some of the best I’ve made so far . I’ve really got the knack of making them work.They are all images of Nebula galaxies and stars at a high resolution.
These brushes are made from NASA images , they have a very open usage policy which is good thing to know about.
