Hi Rocco,
Welcome to the forum and nice pictures. Great subject. My primary comment, and I make it know that I am still learning about exposure, but you shot most of your pictures at f/22 and ISO 1600. You could have opened up the aperture to let more light in and then dropped your ISO, which would help decrease noise, or allowed you to shorten the exposure. Decreasing the aperture may also benefit the image quality in two ways: "sharpness" of most lenses tests to peak around f8 (of course, depends on the lens) and diffraction (
www.luminous-landscape.com/.../u-diffraction.shtml) also negatively impacts your image quality the higher your aperture.
Again, some nice pictures.
