Randy,
First I want to commend you on posting your show. Second, thanks for placing the time in your introduction, I think that helps a great deal.
Your photography is wonderful, but I thought the uneven, uncentered zooms you used (especially on some landscape shots) leave much to be desired. All they accoplished IMO was to draw attention away from your photo and onto the black edges of nothing! One of my pet peeves also is portrait type shots that are left unframed or masked so that the black edges comprise most of the frame. The top and bottom bleed off the frame, and again, the black edges of nothing.
You improved some on this in the later part of the show.
You did a nice job with the 3 framed shots that zoomed in and back, each in turn. That is an example of what I think is excellent presentation.
You might want to download a free program called framefun. It is easy to use and can work wonders giving definition to photos that you choose to have less than FULL FRAME.
