The difference is huge, the second one is way better.
I recommend looking into the work of Will Eisner and Jordi Bernet (adult content warning)
and the way they handle contrast and light and shadow. Jordi Bernet is a good example of
a very emotional / intuitive use of contrast. His shading doesn´t always make sense, he
just puts a black frame around the characters sometimes and leaves out the shading under
the characters (for example), it´s not very logical but works.
Will Eisners work is super pleasant to look at because of the contrast between black and
white and how it makes the characters stand out
