even before I lost my perfect vision I sometimes had trouble finding out why a portrait didnt look right , now in general there are only 2 things that can go wrong: the shapes or the values . values can be checked shapes are a bit harder to spot if they are just a bit off so I cam up with the transparent laminate trick .
You place the laminate sheet over your ref phots and use a CD marker to trace the shape you are doubting about and 2 extra ref points so you are sure you place it the right way over your work.
this way you know what is wrong and if you need to get a shape back you can just place some graphite paper under it ( make sure the sheet cant move ) and trace it back . I use the dark graphite for light parts and white graphite paper for dark parts
