I concur with Tim; the middle photo is very nice indeed, and works great as a black & white image. The other two are a little drab, at least at screen resolution.
Watkins Glen is one of many state parks in the Finger Lakes region, and most of them share its post-glacial topography, with deep shale/limestone glens and waterfalls. I live about 10 miles from Stony Brook State Park; attached is a stitched pano from it.
Most all of these parks photography best in overcast light, especially after a good rain when the rocks are wet and the falls flowing full. In sunshine the contrast range is lethal.
An excellent resource is Matthew Conheady's website, http://www.nyfalls.com/
which has lots of photos and links to maps etc.; it includes directions to many of the lesser known parks and falls.
