I have increased the range of greys available to select from when creating bumpmaps of characters and also provided a number of gradient fills to use. These provide subtle differences in applying the patterned (environment) layer to the character.
I have also reworked the overlaying of light effects on the characters. A new legend is added to the layer stack with each overlay as an aide memoire.
There are lots of options to play with - made myself dizzy trying some of them out with different modes.
Some examples when using the various fill methods for the character bumpmaps

An example of using two coloured light sources: On the left with just a blue light source - on the right a red light source has been overlaid on top of this.
