Editing photo

This is my model friend Carace (right) I took this pictures at night, during a fashion show at Seremban's Era Walk. As you all know when shooting at dark places its hard not to use the flash but the flash tends to make the face on the subject looks shiny. I dont like it and this is my 1st time..really my 1st time editing a person's face to rub off the shine. Its not easy, I tried a few times only succeed doing it. I think the end result is very nice and looks natural. I know that those flash that use by those pro photographer has a cover in front of the flash to make the flash more mild and not too bright. I'm using the standard flash unit on my camera. Anyone know how to get the pro effect ? Perhaps covering the flash with a piece of rice paper ?
