This brush is big (600px)! Photoshop may lag quite a bit depending on your PC's power - this is normal.
Also, this is a brush for advanced users. You'll have to be familiar with the brush-settings or else you won't get very far with it
. This is the perfect time to learn how those brush-settings work, right?
As always, please don't claim it as your brush, you may upload it elsewhere, but please link back to me!
Download should work now, sorry!
