The brushes in this pack have different uses. For instance, a brush to add imperfections can create those ‘bumpy spots’ on the skin, but if you hold the ‘Alt’ key, you’ll invert the effect and ‘carve in’ the details instead. A brush like the ‘Lip Detailer’ can be also very helpful to create wrinkles around the eye or forehead by simply changing the intensity and size of the brush.
The example sketch on the left, has been detailed 100% with the brushes in this pack. Even the polypaint was done using the brushes with the Zadd disable and the RGB enabled.
