Neve, very impressive results and quite the improvement from the original photo! The new brick exterior looks great and the bright blue sky really brightened up the scene. Also that is quite the yard full of colorful flowers!
Two things to think about:
1.
Perspective/Scale. I believe the path would be wider in the foreground and reduce in size as it leads to the house vs. staying the same size. The flowers, especially the yellow ones’, would be smaller in the background and increase in size as they approach the foreground. Right now the yellow flower buds in the background are quite large in scale...almost the same size as a window pane.
2.
Sharpness. When adding several objects to a photo, make sure you maintain the same level of sharpness as the original photo for a more natural look. For instance, there is an area of purple/pink flowers that are in the middle of the yard that are quite sharp, but the surrounding flowers are much more blurred.
