|Greetings from the Critique Club!
Wow, that is some big dude...must be Texas ;-)
This is a pretty decent shot, I'm a fan of low angles and I'm sure this big guy towered over you and family. Composition is very basic, the lighting is quite strong, looks like sun is at high noon, and you've compensated for a low depth of field with a super-fast shutter speed...would have made more sense to go with a much smaller aperture and a much slower shutter.
The main problem here is, there is no sense of scale. And in a Landmarks challenge, you want to indeed show that yes, this IS a landmark...a large, prominent feature easily seen for a good distance around. I don't know what lens you used, but even a basic kit lens usually wides out at about 18mm or so, which would have helped get in all of the big guy and the fair around him to give that sense of scale.
Hope this helps, feel free to pm me
