Out of the two lighthouses, this, I think, is the better one. You have captured a great perspective and I wish I could do water like that. This one goes into the favorites. Nice!!
Nice desktop - hard to pick out anything specific, it's just a good pic that made me go "ooh, that's nice" at work and earnt me some very strange looks from people who don't realise I spend my day looking at pictures on caedes.net....
This is a well composed photograph. It could easily be improved by changing the brightness and contrast levels, sharpening up a touch and perhaps increasing the colour saturation also.
