Is there info on how to make beauty marks and moles any where?

Fill the texture image with dark brown. Open the alpha, then just try placing a tiny white dot. Save, reload the project, and viola, instant beauty mark!

For more exact placement, try importing one of the uv maps for the faces (available here attached to the first post in the thread) so you can see what's what, and placing a white dot on a layer on top of that. Then hide the uv map layer, make sure you have a black background (so you'll have one or more white dots on black) and save that as your alpha.

Common mistakes: making them too big, using black/too dark brown for the colouration, using a completely hard brush with no fuzzy edges to paint the dots - use a brush with slightly fuzzy edges. But otherwise... easy-peasy. :D
