I agree with what has been said already - an excellent picture, and I wish I had the respect for my father that you obviously do of yours. The picture will be a great family record I'm sure, which lets face it is probably one of the most important jobs of photography.
However you have posted it in the critique section, which I don't visit often, but assume means you are inviting us to give our views. Personally I find the tall narrow crop perhaps not the best. I assume you were trying to keep in the handle of the vice, but we don't really need to see that to know what the device is. For showing to people outside of family you have to decide on what exactly you are trying to show. Is it -
1. A portrait of your father, in which case I would have been interested to see more of his face.
2. Is it to show how many tools he has to tackle any job, perhaps show more of the workshop.
3. Showing his skill in putting eyelets in boots, move in a bit closer to make it clear what you are showing.
Hope you don't mind but I have copied your picture and cropped and done a little burning-in to reduce some highlights. If this is unacceptable to you or to the forum etiquette please someone tell me! I can see that you are an experienced photographer and so I respectfully say these are just my subjective feelings.
As a postscript I would also add that the original file when downloaded has much better contrast and tones than than is apparent in the versions here.
