Also you would have to balance getting farther back (increasing the Subject Distance) with the upward angle being smaller.
Getting further away, would be good in so far as it would change the PERSPECTIVE, compressing the Hand/Hoof to Face perception, that would be more 'inclusive' - but - the farther back you move the smaller the upward angle of the camera, so the more the cap's peak is a problem and the smaller area of the window the Blacksmith would block.
Yes it was definitely a good idea getting low and sitting on the floor.
Another option would be to exclude the face - in that case one could shoot from an high Viewpoint and even consider shooting from behind the 'Smith, over his shoulder, (including the back of head or some of it).
Also consider that, shooting from behind, you would be shooting with the light and not into it.
A portrait without a face usually has to be very strong, both compositionally and also Subject-wise. A 'Smith's Hands and Forearms, with sheen of sweat and a bit of dirt and in strong hard light should be available to displaying that strength of Composition and Subject Character.
That is a difficult shot to pull, but I suggest that you think outside the box.
I think it is time to take your candid portraiture outside your comfort zone and experiment and to see each shooting scenario with wider options.
Good work. Much improved strategy and thinking, when contrasted with the images of the Little Girl and the Sheep.
