I like it, however there are a couple of issues I see. The first one (most curious as they say) - your intended show was only about 5 minutes long, HOWEVER, the actual show is 10 minutes - the last 5 minutes (at least in my viewer) are a black silent slide
The second issue was with a number of the images at the early part of the show. I had been going to say they were over-exposed by about a stop, but when I grabbed a copy of the one of the giraffe and zebras, I realized (at least for that one), a big part of the problem was you were shooting through glass and the reflection and ambient light caused a problem. If you have Photoshop, much of that is easy to fix - you open the image, go to "levels adjust" and you will usually find either the white point or black point is wrong (in this case, the lower 20% of the image had no useful data - moving the black point up to the bottom of the data helped quite a bit. A polarizer can really help with reflections, but when shooting through glass or plastic, you have to make sure it doesn't cause more problems - it will also show stress patterns in the glass/plastic (you will see it in the viewfinder) but it is worth having one with you to see how it works. Anyway, I liked it, but the last 5 minutes were pretty boring
