Continue stroking the path on new layers with a 20-pixel brush using colours sampled from the illustration. Experiment using different blending modes such as Difference, Lighten and Overlay as well as lowering their opacities. Now use the Move tool to nudge some layers by a couple of pixels so that they overlap, giving them a more natural look. Next add all the wire layers to a new Group Folder, add a mask and gently blend the wires into the mouse.
Adjust the hue of the hand by generating a selection from its layer, then filling with a mid-purple on a new layer beneath the bones. Set the blending mode to Soft Light and drop the opacity to 40%. It’s down to individual taste on how far you take the illustration from here. Here, I’ve added a pale shadow around the hand and mouse, as well as defining two of the fingertips further with a duplicated masked layer.
