Custom Painting Project on Weathered Barn Wood

I was recently approached by a friend of mine who wanted some redecorating ideas for her bedroom. She lives on a farm in rural South Dakota but she was redoing her bedroom in some beautiful blues with a flare for the tropical vibes. She had this huge wall and needed something there but was at a loss of what to do.

I had this vision of combining part of her farm (the weathered barn wood) with a painted tropical picture and this is what I came up with. What do you think? Does it work?
