This is a rare case when selective desaturation really added something. I would have liked it much more if the reddish whatsit to the left of the reel mower were out of the photo.
Don't think I like selective desat here. Personal thing. I think a little crop on the right may help. Right now this image feels left heavy. Great take on the challenge!
Definately obsolete, but my neighbor still uses one. Technically, the picture looks good. You did a good job on the selective desaturation. I like how the grain in the fence came out. I don't, however, particularly like the post to the left of the mower. It really distracts from the subject. 6
