Excellent photo Shel, very nicely done. It could obviously have benefited from some fill flash to lift the facial detail a tad but overall I really like it

If you raise the light levels of the image overall then I don't think that the hands really need changing much tbh - a slight darkening helps to add a bit more depth to the shadow - I duplicated the base layer & set it to multiply at a slightly lower opacity & then masked all of it away apart from the hands (you can just erase bits of the layer if you're not sure on layer masks - well worth researching though if you get chance)
I then applied a curves adjustment along with a brightness/contrast adjustment to generally lighten the whole image. Another copy of the whole image set to screen & masked/erased so that only the eyes show through added a bit more detail to that area.
Feel free to ask away if I can help with any of the steps above

(Just noticed that you still don't have your "edit" box checked but I've spent ages typing so I'd hate to erase it all now

PM me of you want the image removed
