Oh nuts !! Sorry Kristof, somebody had to do it. Now that THAT'S out of the way, I have to tell you I like the simplicity of your image. Clean, clear & sharp, & yes Virginia, less IS more.
Love the frame .. the fact that you thought to include it, I mean .. when anybody could have told you they wouldn't abide by it, and would tumble out, nay .. break free .. and run
luckily you snapped the image just before they worked up a good head of steam and caused motion blur
Nice composition and yes, the frame works well here.The cropping is a bit obvious in places, esp. around the top right nut. I probably couldn't do any better though.
