I wish I could give you a higher score because your subject is a nice childhood memory for many people. Unfortunately the focus is not up to par. The lighting is ok. There are several thing, IMO, that could have made this a good shot besides the technical flaws. One being a little more creative in composition while trying to make the lunch box (bucket) more of a memory instead of a snapshot. A creative title could have helped.
I no where as good as the majority of the photographers here but if my comment helps in any way and you would like some input let me know. I will do my best.
I wish you the best in this challenge and future ones as well.
The bucket is a bit blurry/out of focus. Sometimes some cameras have problems focusing on reflecting objects... you need to focus manually or focusing on an object at the same distance (to the bucket in this case).
After writing the above i've seen your EXIF... Exposed Time = 1/8 seconds, did you used tripod? If not this exaplains the blurry image.
Gave you a 5.
Harsh lighting giving burnt out specular highlights, distracting textured surface and generally suffering from what appears to be camera shake. A tripod in these lighting conditions is definately a must
