Make a copy of the mask’s layer where we’ve used those three colors to paint the top layer of the logotype. Choose for this layer the Burn Tool (O) and the Dodge Tool (O) to draw several highlights and shadows on the logotype.

Using the Ellipse Tool (U), try to represent the central element of the logotype. Place its layer lower than the top layer of the logotype.

The layer’s parameters: Fill 0%
