well that was a good try! nice rough feel. not entirely sure if that was what you wanted but if so, then you did really good, especially with the stripes and hatching here and there. i would've specifically included some subject matters which people commonly think of as 'rough' like industrial landscapes. you can find some public domain stuff to work with from pexels and then use a local contrast filter or some other detail enhancement thing to make it all grimy like you did here.
