That is looking pretty good! I have never made a "wound" texture although I have thought about it. I usually just add the "stripes" in post work after rendering. When I am making stripes, I use a smaller brush set with minimal opacity and then go back with a wider brush with a lot of opacity to give it that "irritated" skin around the primary stripe. You might try something like that on a texture and see if you like it. If you do, please post, I would like to see the result.
Keep up the good work.
