Think we need more photos to make out the rest of the room. Also need a photo of the reading nook at a different angle.
It seems like the lamp base and the "dinky" mirrors have a similar finish. If I were you I would repurpose those mirrors just cause you have them and there are some similarities in the finish of the two. I would frame it up in using some fabric mats and some rich antique gold/brass frame.

Whoops I wasn't done. The. Put the frame above the chair. That piece of art it peeking out of the little hiding spot it is left at right now. Doesn't do justice to it

Yes, the small mirrors would be better elsewhere. If you like a mirror there, go much larger. A large poster, painting, or collection of photos would also work.

More photos :)

More photos

I would place the lamp more towards the corner, bring the table forward and maybe run the mirrors horizontally.

Looking at the mirrors I do like them very much. I'd frame them up and put it above the chairs. Either an antique gold or the same colour as the blinds.

Do you have more of those mirrors? If it goes up it needs to be a statement not hiding in its corner.

I think the mirrors are too small in scale for that space. A photo taken from the opposite end of that room that shows that entire wall is needed to know what would look best.

A curtain instead of blinds, agree the mirrors are too small. They are pretty though.

Sorry I think I wasn't specific enough when I mentioned framing it. But when I said frame it, to put three of those dinky mirrors in a frame so that you have one larger piece of art. Not having three frames of mirrors.

I'm with charleee on the lamp placement. For reading purposes, move the lamp behind the end table, just off the reader's right shoulder. That will also open up the view of the mirrors, rather than hiding them behind the lamp. If you like that idea, I would suggest you adjust the lamp placement and back up and take another photo and we can go from there. A great reading spot! :)
