The site is quite nice. The initial thing I noticed however was how dark the site is. I would recommend making a redish tint background that somehow matches the butterfly instead of black. This will lighten the tone of the site quite a bit. The only other two things I saw were 1) the white text above the banner, just get rid of it and 2) the links on the right side look a bit odd narrowing down.
Great site though. I really like your work.
