Light on Light

[Terry Johnson]

Hello, I am building a multi-panel image of a lighthouse over-laid on the moon in Photoshop. I am having trouble figuring out how to add foliage (grass, plants, trees) to the foreground that will overlay part of the lighthouse to make the lighthouse look like it belongs where I have placed it in the image. I know how top select objects etc in Photoshop but not trees with small limbs and leaves, tall grass, and foliage with many fine parts. Any suggestions would help a great deal.

Thanks...Terry Johnson
