Good site but I don't like two things: The menu bar, and.... the birds .... that make me think it's for kids
I second what eamiro said. Reduce the number of birds in the background. It is a little distracting. You slider seems like it mixes in with the background due to the colours. Perhaps making them slightly different colours may help. Yes definitely use some other colours that work well together because it is a lot of blue. Also, maybe simplify it a bit. It seems really busy. It is a bit hard to focus on one thing. Just some thoughts.
