Hi, I Was Wondering, How Do You Get Detail In Your Skins? With PaintBucket It Dosn't Seem To Work That Good. (I Use GIMP)

Paintbucket is actually pretty useless for skinnig. Unless you want a blood splat. Always use the paintbrush with the opacity at about 65%. when you're done painting, use the smudge tool with the opacity at about 75%. That is what most people do, I believe. I can't skin well, as I can't really keep my hand steady.

make a new layer in gimp, set its mode to multiply and adjust the opacity of the layer
then paint in this layer over the skin and you will get a nice skin that doesnt loose to many details when being overpainted

Or in Paint.NET use the "recolor' tool at 100 %.
