If i'm correct, then killer is after a 512 set. Had to practice with photoshop anyway so i said i'd rework his textures (not much to do there anyways). Here it is, plain and simple, only better res and matches your lax colour.
In the old textures i was able to make it glow. Somehow i can't find the same option here, much as i looked for it. Still if you like it, i can send it over, basically just two files: one with the crest (for chest&stomach) and one without (leather pattern for the rest).
