That's a lovely place to hang your hat there SeaNile

I agree with you about outdoor lighting, it can sure show a place well.
Any suggestion I would offer is limited because of the single pic to work from.
- But based on the pic you have presented I'd loose the bush marked with a red X - it just seems to through the balance of the home off.
- I agree with the lighting at the base of the two larger trees. I'd probably start with 75w per tree pointing straight up from the base of the tree. I wouldn't think you'd want more then 100w each. Remember you want the focus on the house and not the trees.
- I would put a flood light on each side of the entrance as I have shown with the blue V's. By doing this you frame your entrance.
- By the look of the pic you have to carriage lights framing the door? If there isn't any there I would install a pair. I would also want to pic a pair of lights that give a star burst pattern to them. This pattern of light with it's shadows will separate them self from the ambient flood lighting.
- It would appear from the pic that there is a secondary entrance to the right of the main entrance? If so, then all I would do there is to have a single overhead light that shines downwards from the porch ceiling. You don't want this lighting pattern to match what you have on the main entrance.
- It is really hard to tell what the house looks like behind those trees from the one pic you've provided? But two more floods could work there? Possibly you could even get away with some soffit lighting there to the far right of the house on that gable end. That would look good there. If I went with that type of light there I would not use flooding on top of that.
* Based on the pic that you've provided I can't see the use of soffit lighting across the face of the house - to high and to many windows.
- I would use the same carriage lights that I used at the main entrance to frame the garage door(s).
What I like to see is texture with outdoor lighting. A mix of shadows, lighting going in different directions and different wattages used. IMO lighting should be used to focus attention to given areas of interest at degrees deserving. To me a wall of white light is nothing more then a security measure from the paranoid.
Oh I should add, I would get several extention cords and a few flood lights and play around with locations and wattages. Stick a fixture into the ground then step back to the curb and look at it - at night of coarse.
