don't stagger the lights on the pathway. It will look better if they're all on one side. Can't actually see the walk, but lights would likely look better on the landscape bed side, than on the lawn side. However, (and I agree with the low intensity downlighting suggestion) I'm thinking that with downlighting the front, you very likely would not need path lights. Less clutter and a cleaner look. I would focus on lighting the steps area very well. With that and downlighting on the house, it may be all you need. Take a shop light on a long extension cord out at night and explore the different effects of light shined on various things.

Here is a white brick house with a dark roof. Another with black shutters. You could paint the trim around your window black and remove the shutters for a more contemporary look. If I were you I would change the portico to a gable. You will be able to see your door better and it would look more attractive than the flat roof.

Is the popcorn ceiling a no no? It's outdated & has its issues. But, removal is a project I've avoided! lol! You have a lovely room but you are ready for something different! As others suggest, take everything out, bring in your basic sofa & comfy chair and then slowly add things back in. It will feel odd to have open areas, but give it time. Lighter rug and drapes would make a big difference and the mantle is abit overpowering.

@Paul F. - Are you changing your intended purpose for this room? There was no desk in your original design - it sounded like strictly a bedroom. Not clear on guest room or resident room - but only a bedroom. Now it sounds like you’re planning more uses for the room - combo bedroom / guest room / office? I like the multi use & also the desk plan you drew out. Not so fond of the mock up with screen that you just posted. I think with the corner desk plan you could sit at computer in boxers & not be concerned. If there’s no exterior landscape to soften the view, there are wonderful shades called top down / bottom up. They can cover 100% of window or any portion of top or bottom. They would look much nicer than that interior screen underneath the desk. I prefer the window seat at window or a desk at window with shelving / closets etc on either side & in all cases use the top down / bottom up shades. But, please do allow for a lounging spot for kitty whatever you do!
