This a very well composed image, and all the important bits (exposure, lighting etc) are "right" as far as I'm concerned. I also like the colours with the orange bit of the weight echoed by the (extension lead?) in the BG and it all looks good against the greyish garage door.
Now, Constructive criticism is very hard to deliver, and take! So try not to be offended, I mean to help.
When I ask myself... What is the subject of this image? the story? - I think its like an advertising shot for a set of weights.
I think the focus would have been much better placed on the man, making his resting between sets in his garage the story, with the foreground weight helping to tell that story.
I have looked back through your thread and I think this is the best shot you have shared so far this '52. Keep on working at it.
