How is it likely that we are in his literal image, is there a source in the bible that explicitly states our physical representation of him is meant to be exact? And furthermore what you said about us being distinguishable, yes that's true, most animals of the same species look identical, while humans have many different possible features with none specifically being more "God-like" than what another might have, the hair on our head and face, the shape and build of our bodies, the shape of our face, the different shades of our skin depending upon ethnicity, the differences between our two different entire genders, ect. Our literal image can have 'imperfections' from God's appearance, if must or we would all look identical, yet this does not make us less human, or less of his creation.
If you were created by God and carry the compassionate and noble qualities of him in your soul, you are his child, you are man underneath all, no simple costume can change this.
