thanks guys
I will revise the image to reflect comments and see what we get.
I didn't crop because I wanted the 'negative' space to add mood and aid in focusing the viewer. Re, lighting, yes, a slight re-adjustment is needed and should enhance the image.
Yes, I used an extreme wide angle to get the portrait. I was torn between a classical portrait and 'environmental portrait' - I wanted to capture the context as much as the person themselves. Perhaps some distortion correction is warranted, although the large hand does provide some abstract value (triangle between the hand, head and candle with bible in the centre - analogy for the holy trinity ........ abstract).
