You're ugly and your mother dresses you funny!
Okay, now, C&C Per req:
1. Well exposed but very flat lighting, I'm guessing the sun was fairly high in the sky? Try and avoid lines that take your eye out of the picture; in this case they're not too bad because they're a fairly wide band.
2. Nicely done, but a bit busy on the left.
3. Again, fairly flat lighting
4. Very nice.
Just my $00.02 worth - your milage may vary.

Thanks a lot John, you're absolutely spot-on. I shot the first couple at 4-5 in the afternoon. I'll have to go back a couple hours later next time, maybe even this week.
