Just taking pictures of a clean house, even relatively clutter free like yours, is not the same thing as selling the house via photos. Your agent has done a very pedestrian job, which is a shame as you are 'motivated' sellers and with better photos, a faster sale at your original price would have been better commission.
You can take better pictures yourself if you cant get him back in with a commitment to work on them as more than a box ticking exercise. Study websites to get good ideas of angles and lighting, hope for a sunny day. You may need to buy or borrow some set dressing items, like bedding. Dont use your phone unless you must, even a small digital camara would be better. Plan to devote a whole Saturday to this. Get somebody to take DCs for the day, get someone who can help move furniture. Your goal is pictures that make the rooms look best, not to document your furniture layout.
You dont need to buy a bed. Do you have a full size bed in the other room? You only need to borrow or buy a second set of bedding to fit that then. Or if you have neighbors you know well enough to borrow a bed, and bedding, do that. Maybe someone would loan their bed if you bought them a nice duvet set since you wont need it after. (Set a price limit! )
Move your bed into living room. Move second bed into bedroom. Make up bed nicely. Consider what else needs removing /improving. Should there be a lamp there? Move one in from another room. Take pictures, a LOT, from severy corner, high and low. The current picture is out of focus, poorly lit, and seems to gave been stretched in photoshop. All are bad things. So, now you have better bedroom shots. Swap everything back where it belings.
Get nice pics of the other bedroom, and the bathroom while you are at it. If 2nd bedroom is DC, remove ALL toys and things like boxes of nappies. Dress the room with minimal stuff, take pictures, put stuff back. Ditto bathroom. Nothing should be visible except fresh towels and a fresh bar of soap. Make sure the toilet lid is closed.
Consider rearranging living room to look less crowded, including moving some furniture out entirely. Doesnt matter if the TV cant reach the cable point or that you dont want to face that way. Set it up to look spacious, take pictures from multiple angles. Be sure to use the window bay as, from the right angle and including that, the room could look huge. Then move on to the kitchen. Get a picture of that without the lamp in the way! Looking the other direction, and including the bay would make it look larger. Should the bay be 'dressed' as a dining area?
It's a lot of faff, and there will be the trouble or expense of borrowing or buying some stuff. But if you want to sell fast, the expense is probably worth it.
