Have a look at an awesome pack of cheat brushes for Photoshop CS6+ by Marc Brunet.
“Need quick female hands for your characters? Well, now they exist in the most convenient format ever, brushes!” The artist doesn’t recommend the pack for beginner artists unless it’s for study purposes. It’s perfect for professionals who need to save time.
The set features 10 different brushes in poses that the artist often uses for his character designs.
