A simple first step to improving the photographs would be to use a polarizer, for all your daytime shots. If the store sold you a UV filter (to protect your lens), chuck it. The camera shop was just looking to make a few extra bucks. It is cheap glass, in front of your expensive glass. Cheap glass ruins photographs. Buy a good quality polarizer, and try turnig it to change the amount of polarization effect on the image.
If the sky is not interesting (clouds, etc) include less of it. If you have a horizon line (Lake Erie in this case), place it at the upper third of the image, or lower third, depending on how blah the sky might be.
Place your subject right, left, up, down; but not in the center. Rule of thirds is very pleasing, most of the time.
Last, but not least; photography is the capture of light. So; bad light will make for bad photographs, no matter how beautiful the subject. Stormy weather is usually more dramatic than blah, clear skies.
There is more; but this will keep you busy for a while.
PS: If you are using a point & shoot camera, many of them have an adapter available, for attaching things like polarizers, and other lenses.
Great trip, great reading. And VERY cool rig. Thanks
