Photoshop grass - kill it with fire!
"People use it even though it's like, got no lighting direction, and it all points the same way. :0"
Yes, we all had lack of experience so when you're only a begginer in working with PS it's fine to use it.
But when people with good level use this damnit brush i want to kill them. This is a thing that can kill your picture no matter how good it actually is.
Stamp is free to use.
