Hi Spencer, A Par 20 lamp is too long to be aimed at wall art in a 4" housing. It won't pivot enough without hitting the side of the can. How did you aim at the walls with what you have now? Nora must be including a short whip with the slot aperture trim to convert to a line voltage GU10 base MR16 because that type of slot aperture trim only works with small lamps like the MR16. Check on the adjustment range for the trim and wattage limit with the combination. You may be limited to 35 watts. To dramatize and call attention to something accent lighting needs to boost the lumens on the subject well above the surroundings to bring your eye to it. You may need to dim the center fixture to help compensate so that the art stands out if I understand the look you want of spotted paintings glowing more intensly than the surroundings rather than the general wash of light you have now. Different brands and styles of trims have different ranges of adjustments. Normally the slot aperture has the largest of the adjustment ranges and may go to 40 or 45 degrees without blocking the lamp so this should be a good choice. Other trims claim 35 or more degrees but may partially block the lamp.

How about some elegant black iron scroll work? There are scads of varieties and they are often the perfect solution for a wall that needs that certain "something". (The photos are from my home.) I recommend choosing art that a) reflects your interests and b) makes you happy every time you see it. You said you can't your hang travel visas and martinis, but why not? You could frame your travel visas and arrange them under a large matte. For the martinis, you could either buy a painting or print of them or literally frame some martini classes in a shadow box. You might also consider vintage travel posters from places you love or that you've already been to. Your home is very nice!

I love gray but I love the look of white with black doors..can give a modern farmhouse style...agree would be nice if rails could be put in but if not in the budget I would go full on......modern farmhouse....add a stained wood ledge top for railing.

I don't mind the table and mirror and can't really think of anything besides art that would fit on that wall. Can't see the table details well but could it be painted? How about red to match your lovely door? What would say "fresh and cozy" to you for that space? Have you thought of a new light fixture? A runner and a larger rug in the entrance could look good. I don't find the clock visible from the door to be welcoming so I'd be tempted to remove it.
