This is the brush I used in my painting The Dwellers
Just to let you know, I also painted some grass blades in by hand with a small brush to give it more variety ^^.
I made this with Photoshop CS3 so... I'm not sure how well that meshes with other Photoshops. I think, if I'm not wrong, that all the CS versions will be able to use it, but I'm not sure about anything earlier than that. Sowwy.
This is my first time uploading a brush so... I hope I did it right. o.o
