Anyone want to play with a beach photo?

So my DH and I recently remodeled a little lake condo, and I want to add a few canvas photos to the bedrooms of beach/vacation photos we've taken over the years of the kids. The ones I like are so drab, and I think when I enlarge them, they won't pop like I'd like them to. I haven't played with photoshop in so long, and it's driving me crazy that I can't seem to enhance them to a quality that would work to print an enlargement. Would anyone like to give it a try? I could send you the largest file I have, but I'll put one here to ask if anyone is so inspired. Thanks in advance, and any tips would be also very welcome!
