Wow Varm the first two I LOVE!
the tone is really nice... and i especially like the poses in the second one. but you might want to rename to 'cowgirls...and a boy' lol
the third one of the outhouses isn't as strong imo. i see the humor in it and the composition is neat with them all in a line you know but it looks really flat. I just took it into PS and messed with curves and upped the contrast a bit and it looked more pleasing (to me).
The rodeo clown - I like the colors in it (as you probably knew, lol) but there's some noise and grain. The objects behind the clown are really, really distracting to me. I find myself straining to find the outline of the clown (which might be due to overexposure). Did you happen to get any other shots of him? Maybe a little more isolated. I know that it's so hard to get things perfectly set up for things like this.
Great GREAT job on the first two though... absolutely wonderful!
