Yes indead, I noticed while I was making them. Already made the barrens map, some tiles here are well made and don't need repearing but there are a fiew that needed fixing, also remade the bumb for all maps, hope it looks good to you. Noticed another thing, the alfa mask was wrong, turn your lighting and contrast minus a notch in photoshop, made the specular color a little to white and looked like plastic, I'l explain when I get back.
The ashen ones need a comple a fix.
