These would benefit from a different sizing and sharpening for the web. I can tell that they are in-focus and all, but they look..."fuzzy", as if the originals uploaded were too big, and somewhere along the line, re-sizing and or down-sizing and compression has basically ruined these. How large a dimension are the uploads you send to your web host, Ed? I'd try going with 1200 pixels wide, and already sharpened with unsharp mask. "Big", as in 24-megapixel type big captures often look wonky when shrunk down from full-size by web hosts.
