I can't say much about the exterior because I have a completely different taste in houses. Regarding the floor plan, I notice (as far as you can say without dimensions): pantry with a window, and only accessible from the kitchen through the hallway? That would be too impractical for me. Huge kitchen, living room difficult to furnish, and then only space for 4 seats? Don’t you want to sit there with more people sometimes? Bedroom relatively small, you don’t even have space to put a dresser. I also find the guest room in the basement difficult. If someone stays overnight, they have to climb 2 flights of stairs to get to the bathroom. I usually find self-designed house plans difficult. If I were seriously interested in building, I think I would look at designs from architects again.
