This is NOT HDR. I did run a 7 shot, 1 stop bracket to make sure I had what I needed, but the final image was made from a single frame and processed mostly in LR. It's pretty dramatic (maybe too much) but my client loves these. Just throwing it out for comments.
Good job being able to use a single frame without any exposure blending.
The tough aspect of twilight is deciding on your White Balance. It looks like you went with daylight which made the lights pretty orange. It would have been great to see it at 4000K so the tungsten was a little whiter and that would have intensified the blue of the sky.
But none of that bothers me as much as the brown grass. I know it's Winter but it's screaming for some color.
Lucky to have such a great sky to shoot against! Otherwise, I agree with Daniel's comments. Also, the lighting on the house itself is very flat—I'd love to see more range between the shadows and the glow of the lights. That said, I totally understand the desires of realtors to have everything so bright...
Love the sky, but loose the tree and supports on the right, they take away from the image. Edit out the power pole on the right horizon, just some clean up to take away the distractions.
Great angle, it is a bit dramatic but this stuff sells and works great for agents. I agree with Larry. Also the hose, always hide stuff like that or Photoshop it out. Not much you can do about the grass, if you made it fully green that would be going a little too dishonest. The interior lighting should be uniform. Its distracting that the right side lights are on and left side aren't.
Nicely done. I tend to like the daylight white balance with the warm lights, but agree that the left interior lights should be on as well. One thing I do is wet the concrete (entry, sidewalk and driveway) just before the shoot - gives it a nice look.
