Not sure your original selection is the right item for your fireplace. The fireplace is long and narrow, so why add a piece of art that is a rectangle, inside a rectangle, inside a rectangle placed on a rectangle. You need some movement on this wall. Maybe a triptych of framed art, maybe a selection of three dimensional items, maybe a selection of round primitive baskets, maybe a twig sculpture with some movement. Get creative. Think outside the box.

Be careful not to have so much going on, that your guests are having to constantly be looking to see what the next whimsy will be. Sounds like simpler is better. The fish are fine, but is there a nautical or fish theme going on, or is it just another decor item that may not relate to what you already have in the room? If your art on the other walls is fish, or something like that, it seem fine. but if you have the Mona Lisa on one all, an image of castles on another and dogs playing poker somewhere else, it might be time to take every thing down, and try to come up with a theme for your art. For my clients, I always try to group similar things together, and work with colors that are already in the room, the rug or fabrics.

Thanks everyone ... I appreciate all the help and compliments I received on this! The rug isn't new, but it was my 3rd try until I got it "right" You know I didn't even think to move the picture up a little, to cover the box, but I will definitely do that. Unfortunately my whole house needs to be rewired, so I will have many more of these type holes to patching paint!

Google the artist and discover his works sold at auctions such as Artnet.com. No clue if this particular piece was reproduced. Mr. Goose passed away in 2001 from what I read. Alternatively, you can comment on the article and ask the designer where she sourced the piece. Might have been a gallery selling his work or might have already belonged to the homeowner. The gallery might have other works of his you might appreciate. Btw, you’re posting to a user forum made up of decorating amateurs and pros, not writing to Houzz staff directly. :) Hope you find something to your taste. That is gorgeous art in a gorgeous room!
