I think you did a good job all you have to fix is that brownish sky, but that can easily be changed,
it shouldn't take you but 3 to 5 min.
just add a different sky to it and mask the house out, leave the trees alone, then set the sky layer to Darken Blending Mode this mode will look for the darker colors in both layers and leave them unchanged (in this case the branches), it will only replace the lighter colors,
this trick will avoid the hassle of trying to mask out branch by branch and save hours of time !
here's what I explained, you might or might not like the sky but it was for explaining purposes
