I really like the forest painting, I’m just also thinking of adding a rug so it might mask most of the floor. Any ideas on something a little brighter?

Following

Rug first..... then art....rugs to love ....are tough to find ....so choose price range first ...then size....then colors...the nicest material is wool as it looks richer is easier to clean and lasts longer...hand tufted is the most economical...and 1/2 “ thick is elegant and less likely to trip on....there are hundreds and thousands to choose from on reliable websites ...keeping in mind it is easier to keep clean if there are multiple colors and a smallish pattern....so once you nail that down you have the foundation for the style and art choices for the room......when choosing size keep in mind you will want the rolling chair off the rug enough roll in or out on the solid floor...or all on the rug...this will most likely be your biggest investment so don’t hamper your choices by beginning with things that need to match ...like the pillows and art

Adding the right rug will definitely make your home more inviting...and set the pace for the whole room...with the added plus that a good one will go with you to all your future homes

following...

floor plan and measurements will help pick rug size. budget helps too.

Have the measurements for your art in your wallet,too...look at street fairs ...thrift? stores and off the wall places ...for original pieces ....if that is your taste...sometimes it is a piece of antique textile?....an old metal piece you can spray all black?...an old ornate frame?...

I often re-read initial post by OP - I notice now that you won't keep Buddha... [you still like bit of gold, got that]....

You could do well with a mostly neutral rug, and keep adding art: sofa, over small desk, etc... here's just one, 40 x 60"

I have a feeling this space could be utilized a lot better. Before you get art, rug etc. let’s fix your layout. If you are open to rearranging furniture could you make a rough sketch of the walls with lengths, openings and lengths and depths of sofa and other pieces you need in this space. More color would really be pretty and help left the look of the space. More photos from as far back as you can will help me see your “lines of sight”. Bbl

Small space with several elements, I'd probably prefer an organic look, also to let the brick and counter have the attention more so - can have shine of gold too...

I agree with Flo. NYC apartments are usually space challenged, and yours seems true to form. I’m trying to figure out the relationship between couch and desk and hall.

Your art over the sofa should cover 2/3 - 3/4 the sofa width and hang 5 - 8 inches above. I’d do a square or portrait format canvas or print over the desk. If you want a bit of bling there, try Great Big Canvas’s metallic art: https://www.greatbigcanvas.com/category/art-by-color/metallic-wall-art/gold/?pagesize=90
