Here's one of mine where the lighting started out as one of his Beautiful Nudes light sets. Those particular sets are set up for particular poses.

You can go to RDNA's store and look under Colm under the vendors, I believe he's the first one.

Most of his stuff is good, I don't personally care much for the GI Studio or the IDL Lighting Rig, but that's mainly because I don't care for using light emitting objects for the main lighting.
My opinion is that good lighting can make a mediocre render look very nice.
