Don, welcome. Idaho Falls is a great place!
First, it's great that youre getting out and taking photographs of the things you love! It's a wonderful experence, aint it!
If I had one bit of advise for you it would be to FOCUS on the subject, and try to express somthing in the shot. What you have is a number of shots that capture a time and a subject, but lack a message. Take the goose shot for example. It's two geese, and some other ducks around the edges, photographed at the human eye's perspective. I think ducks and geese have to be focused at their eye level or below (for flying birds) otherwise they look like ducks in a park. . . So, crouch down to shoot ducks - and any most other wildlife for that matter. . .
The cat shots are similar. Cats are predators, they are best photographed at eye level or below. And, you should focus on the subject of the shot and then snap the shutter. Again, it looks to me like you were rambleing by and took a picture of a cat in the zoo. I can imagine it's tough to get good shots at the zoo (I've never been to one and taken photos) so it may not be possible to get the feeling you want from a zoo shot, but the rules still apply.
The falls shot topped the building, it would have been a better shot had you left attached the top of the building - so, since you chopped it off, I'm left to think about what you are trying to tell me, is it a shot of a pile of sticks jamed in a manmade diversion? or is a landmark among landmarks in the Idaho Falls area?
Finally, light and eyes are the two most critial aspects of wildlife photography - after compositon, and equipment. So, try to shoot durring those early and late periods, and know your equipment and learn animal behavior!
Keep it up. . .
