Really nice job!
Just one small, and probably annoying, bit of critique is that the scratches look like scars in some areas. Scratches are mostly thinner. Here it looks like you found a scratch map or made one, and scaled it up, which made your scratch width a bit larger. But then again, it could be wide things scratching your surface!
Awesome job though. Like I said, it's a small critique. Even if something's perfect, I'll still try and help someone out
