What to do with this boring large wall

[vegascouple]

It's painted in F&B Hauge blue, I'm just at a loss.
It's quite big and looks so empty and ridiculous, I'm thinking industrial looking shelves, an animal head (metal or wood) but I've not idea where to get reasonably prices ones.
Any other ideas, throw them at me.

Gallery wall? Lots different pictures/art/objects. I like it

It'd only take 20 years for the DH to put them all up 🤦🏼‍♀️😂

Ikea and Matalan have nice art. Or look for an artist you like and buy one of their works?

A vintage shop may yield something unusual.

Is that a fireplace? Could you make the hole a bit bigger and fit a hearth and mantelpiece with a nice mirror over? Will break up the space and provide a focal point.

What about this art work from next

Saw it the other day and it's quite large and would look nice against the blue. I'd also think about making the fireplace larger with a surround of something like that.

Yes it's where the old fire was, we've just renovated and eventually will be putting a log burner in so knocking walls out isn't an option unfortunately, just going to look at links now

Yes I would go for gallery wall as well.
Some sort of eclectic/assorted style, kind of mixture of family photos and art.

Something like this.
