Every time I hit the homepage, I get the same waterlillies image as the background, yet looking at the galleries there are much stronger images on your site.
I wonder why did you choose that image as the showcase of your site on your homepage rather than one of your other images?
Not saying the homepage image isn't good. The reflections give the water an almost painterly look, with the contrast of the very distinct and clear leaves. Just to me, there are much stronger images in your galleries, including in the nature gallery where that waterlillies image sits.
