How can I add dimension to the exterior of my long, flat house with shutters, rock garden bed edges, new paint, gutters, and changes to the front door color?

Hey everyone!! Just finished redoing the inside of our house and now I’m stuck on what to do with the outside. I’ve been staring at it for so long that I can’t seem to come up with any ideas. The house is pretty long and flat, so I’m thinking of adding shutters and some rocks to give it more dimension. We’re also planning on moving the car port and getting new gutters. Any suggestions on paint colors for the siding and trim would be greatly appreciated! I’m even open to changing the front door color. I’m also considering washing the brick. And if anyone has any ideas on what to do with my random sidewalk, please share! Thank you all so much!
