Try blurring the render layer and then set it on overlay using the blur tool? Im not so sure if that helps.
I have made some changes on my latest sig. its more easy on the eyes now and not too bright. also sharpened a few parts. Hmm.. I have considered using photoshop but I got overwhelmed with so many of the tools you can use. Been thinking about it lately besides using gimp to make all my graphics works which Im use to.
