Love the werewolf concept , but I feel you could go more aggresive with it imo example: http://th00.deviantart.net/fs71/PRE/f/2010/079/3/8/WEREWOLF_3_by_el_grimlock.jpg
Don't want to be an ass, but your slardar back armor looks a lot like my back armor for Slark. If I take a look at your concept it had been a crab shell, and now it's a lobster shell with exactly 3 pieces? After Vlad's last thing, I just had to mention this because it's nothing like your original idea, and I'm not sure…
