For the head mtl I will suggest my standard comment: Lower the ambience. That's one primary reason a lot of objs look washed out. Make the ambient color darker and lower the ambient value. If that's too much contrast work your way back up until you get a good balance. The lighting may be a bit flat. Too much coming from the front and flattening out the other shadows you're getting from above. Get the Head TR map that came with the poser head. You'll find it in Poser/Runtime/Textures. Select the eyelash mesh in bryce and set the transparency to use that map. Set the mtl to blend transparency (rather than additive). Last but not least, the color texture for the head, you might want to try varying it a little more, so its not all one homogeneous color. Did I say a few suggestions? You're intent (by your telling) came through loud and clear so congrats! You're description matched what I saw.
