The background looks very heavily recovered, too much Shadow & Highlight manipulation I'd guess, which has given it a rather surreal look, but it looks strained because of the over aggressive levels adjustment. Good composition, and nice model
Good color combinations and nicely composed. Considering this is a setup shot the ocean horizon should be level. Looks like you might have used Shadow/Highlight in Photoshop CS2 or some other contrast/lighting enhancing tool. The resulting halo around the lighthouse will be considered more distracting than enhancing by some voters.
