If I were designing your system I would use MR16 spot lights on horizontal picket fence. Flood lights on the broad leaf palm trees two the left of the fence. I see a tree I would put a spot light on. A few path lights on the concrete walk ways.

Path lights that have a flat "saucer" shaped top will give much better coverage that a pagoda style path light.

I would also put a down light off the second story shining down on the patio area where a door is pictured on and inside corner of your home.

Spend a little more on some professional grade fixtures, they're worth every penny over the common big box store grade fixtures.
