A dark quartz countertop could give you great contrast if you plan on keeping the lower cabinets. Quartz is one of the most durable, can take a hot pot, doesn't scar and requires minimal care. (All other stone types have limitations and require extra work.) Daytime photos would give a better idea of what you have in the way of upper cabinets and light fixtures, how much light you get. Also, need some comment on your decorating style -- modern/cottage/traditional, etc. -- and color preferences. What rooms does this kitchen connect to? In the meantime, look into replacing the cabinet doors. These look somewhat 70s, and you may enjoy a wood or a color. There are a lot of companies that specialize in refacing cabinets. Some glass doors might be interesting. Search houzz for kitchens you like; that will help you focus on what changes you want to make and will help us make suggestions.

@ Hilda Tinkle...LOVE your room...mostly love the rugs and, in my view, those artworks are as if they were purpose commissioned ! "The whole" I am sure reflects your personality! Its been very interesting watching it all grow. As for replacing the lamp stand, personally, I really like that stand both for the room proportions and... for that friendly, substantial chunky lamp. I feel...and that's "feel"....that I'd want to put some sort of novel,decorative, low, longer, narrow, open construct couchside table/magazine/book 'depository'/drink putter-on (phew) at the side of the couch ...a proportionate space away from the side of the couch...something that has room for the lamp at the end to sit exactly where it does now under the yellow painting....Or, keep the lamp stand where it is and add a little bit of decorative yet functional whimsy at the couchside. It would need to be the perfect thing...I see a little nest of small decorative tables in my mind's eye...just feel you need to relieve the substantial solid feel with something that looks light and.... airy?....hard to describe, just a mind image. How about one larger cushion among the array of small ones? I've not seen your room for a while. I love what you've done..dignified, furnished in quality items and more to the point..themed ! Imagining myself relaxing in that room along with a friend or two....find myself wanting something tall that draws focus, maybe that accentuates the purpose of the room or calls attention to the theme...just a thought. I spent my early childhood in the Pacific and was surrounded by artifacts and furnishings that had the same "feel" as your room. I am really impressed by your attention to detail and how you've managed to assemble it all so it appears purpose made to go together, Congrats on ...substance ! Where did it all start...I've forgotten....with the rugs?

The photo below is my suggestion for colour of floor. Furniture should be darker - similar to below. For the rug - choose one colour from the artwork and find a similar coloured rug. Don't put a mantle over the fireplace - it could be a health hazard - bumps and bruises. Blinds - unless you want them to make a statement I think white - to match window frames would be fine.

I would vote for the top example here. Itr gives an earthy tone to the room and yet is still bright and wont show every piece of dust or food.
