George,
Those are some fantastic forms.. really like the shape and texture of them all.. I'm less enthusiastic about the carved pieces, but they are great too.
I just looked at your website very briefly, and on my monitor the pictures are dark same as the ones you showed above. I think I have to agree that they do need a little tweek on the brightness. I have Picasa 3 on my system, but don't find it all that easy to use... mostly it just sit there and I use a Microsoft program I picked up some time back... I also have another program I use occasionally, depending on what I need to do.
