I used a gold layer and grain merge for that. It seemed to be the best way to do it. Layer opacity well down.
I started playing with the detail level decompose after seeing it on Pat's blog. I don't generally use select and blur though. Things vary and I find the thumb better. I tried it for very selective sharpening as soon as i realised what it did. Jiust doubly a layer. Even a layer that has detail that can't really be seen makes a difference.
The skin tone was odd. My EM-5 has never produces one like this raw does so I just fiddled with chromasity in RT.
The dodge and burn method came from this video.
I'm impressed it's way more controllable than the usual dodge and burn. I used the thumb and eraser on this as well and a separate layer for each feature change. I found I needed about 40% opacity in the GIMP and blurred by looking at the layer itself and also used brush shape and opacity at times. It would be wonderful if the GIMP kept the changes in history so that things could be gone back to and changed from the setting last used especially things like blur and curves etc.
