I'm currently drawing Wonder Woman with charcoal. While drawing I noticed that the armor has scratches:

Since it's a charcoal drawing, I'm having difficulties, because when you use it, you blend it (I think, as it works for me), but the armor has a weird texture like if they drew it with pencils, not charcoal, I don't know if I'm being clear, I don't know how to draw that texture.
I'm using 2-6B charcoal pencils and hard, medium, and soft charcoal sticks and graphite to make it smoother.
How can I properly draw those details (scratches on the armor)?
