Took me a minute to find the larger sized pics, had to click the "View Multimedia" link above the smaller pictures on that links page.
Having been a realtor for a short time and seeing lots of houses. I think yours looks really good. One thing that caught my eye was the plates on the soffit in the kitchen.
The thought I had was "that's a lot of holes to fill when those plates come down". Only reason I bring it up is that we had a house we sat on for 8 months doing open houses almost every weekend for several of those months. Out of 155 showings the only comments we had over and over were that the wall paper border on the soffit and purple paint in the kitchen made it look dated. My wife finally convinced the owner to remove the border and paint the kitchen a neutral color. The house had a contract the next week. Point is, people just can't see past some things and secondly they don't want to do anymore than they have to on a newer looking home.
Be sure you have a new furnace filter in the furnace, take some cleaner/paper towels and detail the furnace and hot water heater inside and out to make them look brand spanking new, even in the area where the filter goes. Clean up the floor around it and get any dust bunnies as well as the gunk in the floor drain. I know mine by the mechanical builds up dust and gunk over time from the condenser draining into it during the summer months. Big concern with folks is making sure the mechanical is in good condition. If it looks that way than you've settled many of their concerns. It takes away negotiating power too if they can't say it looks like it needs a new hot water heater.
Overall, if you're not getting any bites, listen to the feedback and it may just be something as simple as a border or paint that is enough to get the right buyer in (though I know how much you like painting).
P.S. Is the living room a textured ceiling and the kitchen not? It's not a big deal, but something that caught my eye, just never seen it done that way before.
