If you lack/cant find a picture for your suggestion, please take a look in here http://www.conceptart.org/forums/showthread.php?t=37514
Though you still have to tell what your idea with the appearance is, as we notist differend things in a image; f.x you post a picture of some huge troll and like how it looks with muscles and size but then i look at it and see the hairstyle and oversized hand and that it might have a big belly, which i then focus more on then the muscles and size.
Have to say that it might not look 100% like the one that suggested it want it to look, as it have to fit with rest of the world.
