A very good framed photo,it has a very nice depth i think and yes grain is a very good idea.I think two grain layers multiplied or color dodged would make it even more realistic.Very good work.. ;)
This picture looks like it was taken in the 1920's. Maybe if you had gotten some darker shade of grain in it, it might have looked like it was taken back in the late 1800's. This is just a thought, your image is beautiful. Going in my fav's w/ a vote.
