I suggest you down load the most excellent Vicky Buster texture. Use that as a guide for your freckles, SnowSultan had an uncanny knack for applying just the right type of skin textures for the body. Mason is right on track. Freckles are much more pronounced in areas that are exposed to the sun and much lighter and less dense in the areas that are not. Using the Multiply setting on your layers rather that the normal additive mode will help with this.
