It's a good first try.
In the first photo you need to straighten up those verticals and cool down the yellow tones a little bit. The exposure is nice, not too bright, not too dark. Nice job!
The second photo also needs to be straightened on those verticals. Turn on the lamp to add a little more warmth and light. The image is a little under exposed. And, here is the more technical side, you missed the focal points of the room. The two foreground chairs dominate the photo and take away from the wood floors and the fireplace. Try to focus your attention on the noteworthy features when shooting a home, not just the room itself. A different angle shot from lower to the ground would allow you to get more flooring and the fireplace. These are things online buyers are going to be drawn to, so try to get them in your shots when you can. I am also a Certified Residential Appraiser, so I am trained to spot the noteworthy features. Then, I make sure to get creative shots that focus on those features, especially when I know it could be what makes a buyer come see the home. The more you shoot the more you will start to notice these things. Also, it never hurts to ask your client 'what are the most important features of this home?'. The more you ask this question the more you will understand what sells a home. Once you got that down, your photos will impress buyers and sell homes.
