The amelanchier does look good there, and will certainly fill in nicely. I originally backed the cercis canadensis 'Forest Pansy' for contrast, but it does look nice as you have it. But perhaps the rhodie corner can host a japanese maple (acer palmatum) for that contrast--maybe a weeping variety would be nice. There are hundreds of choices there, and it's tough to go wrong.

Hey, that's great! I am also springing for the upgraded electrical for an induction cooktop. Based on my use of a portable unit while we are sans kitchen, I think it's a great decision!

Nursetammi, instead of messing with the trim--because you're not really ready for that, why not paint the walls a similarly medium-dark-to-dark color that looks wonderful in lamplight, makes the trim a quiet detail, the whole coordinating with the kitchen wall at the other end? Very significantly, erasing most of the contrast provided by trim and possessions against light walls, so that your decor blended harmoniously, would keep the richness they bring but lose any feeling of clutter. This is why so many of the rich old layered rooms were in dark values. To me, going this direction would only build on the inviting coziness you've already created in that area and make it a very appealing alternative to the brightness of the seating area by the kitchen. Most of my house is white with whites because it's not that large and I like that, but I think the trend for almost exclusively light walls in this era is regrettable, causing people to miss out on some very special options. http://gossiplankasinhala.net/wp-content/uploads/2016/07/Dark-Green-Living-Room.jpg

Pictures would help; there are so many different types of “paneling,” I would want to see what you’re working with.
