|Greetings from the Critique Club!
Bonjour Marcel, comme ca va? (Sorry I can't get all the accents in where they should be ;-). Your English is much better than my French or even Franglais will ever be!
Very nice photo, well thought out with a nice, big, detailed wagon wheel dominating the image. FWIW I've never before seen a wagon wheel with those sets of double rivets before, and I've seen a lot! Good leading lines leading to it, good exposure, good use of thirds. I am glad that the small glimpses of houses seem to be older houses, and not very modern ones, which would ruin the feel of this shot.
I have to admit that I am not a big fan of vignettes, so many bad photogs use them as a crutch to prop up their own work, hoping to awe the viewer with a vignette. I don't think this image needs a white vignette; though I don't hate it, I can't say I'm a fan of it either. A commenter mentioned a dark vignette. Might be interesting, if you still have the original image, to dig it up and try it with a darker vignette and see the difference. Could make all the difference in the future!
Hope this helps,
