personally I dont like lots of metal stuff, I like more organic looking models, I have yet to see a fantasy pack (weapons people plants small buildings) with full normal maps, and specular maps, that looks nice and that the normal maps look realistic on. Most people for some reason think that because it looks good on metal that it will look good shiny on everything else

Again tho, this is amazing work, and even in a saturated market, these can definatly be considered high enough quality to sell very nicely.
