First attempt at distressing

This was my first attempt at trying to make-over an object to look old and distressed. The frame before wasn't bad but it was silver and somewhat modern looking. I never displayed it because it didn't feel like my style. Now I love it and it makes the old black and white photo of my grandmother look so adorable. Any tips from you experts out there on how to do differently/better in the future? I'd love the advice.
