actually, i recomend getting paint.net, select all parts of the skin that should be shiny cut and paste them on a new layer, then turn the layer's alpha down to about 150, and you should get the result your looking for, if you also want a bit of a specular shader with it though i can give you mine, it's not perfect, and it doesn't support dynamic lights, unless you use blocks, then it supports dynamic and static, but it looks good:
