Automatic shading filter

Hey guys!

So ehm, here is the overlay that ive used to shade my skins for a while now. i know its not really a skin, but i thought id share this with you guys.

Notes:
this does not work perfectly on all skins.
I use paint.net, names might not be the same for GIMP or so.

How to use:
1. open file you want shaded.
2. create a new layer and paste it on there.
3. go to layer blend mode and select overlay.
4. choose the oppacity you like.

You might wanna add a bit of saturation after the whole deal.
