Nice looking site...great job. I'm on the fence about the blue background -- my personal preference is a gradient gray, but a lot of folks use that.
One suggestion would be to crop some of the pics a bit to center the piece in the frame better. The first picture in your gallery is a prime example of this. You could remove the top 50% of the frame and have a better shot IMHO. The extended blue to black background above the piece adds nothing to the presentation, and in fact wastes pixels that could otherwise be showing off your fine work.
Also, I don't know if you care, but you are saving the pictures with some additional information, which allows other to see what type of camera and settings you used. (How do you like the D40? I love my D50.)
To see what I'm talking about, you can right-click on the file in Windows Explorer, select
Properties, click the
Summary tab, then click the
Advanced button. If you save the file with no "EXIF Data", that data is no longer included in the picture file. I haven't used Picture Perfect, but Irfanview (a freeware graphics manipulation program) has the option to not save that data. You can get Irfanview at Irfanview.com. (No connection to the company, but I use the product almost daily in my work.)
Again, great site, especially for your first stab at it. (Way better than mine.)
