Oooh, I love Deathstroke also! His outfit looks neat, but maybe the Mask is the trickiest part.
Also Killzone styles for coats and suits look awesome, Orlock's coat also seems pretty warm. Stahl's tuxedo looks fancy also, but in my case I have some cosplays that I couldn't do due my shedules! Apart from capture trooper project I was also looking for an EVA 01 cosplay, but I just don't have time for an armour cosplay :c
