I like the lower one even though I try to stay away from the symmetry because I don't like to think about death.
I like the bottome one with the top darker blue of the top one on it.
To be difficult I like the top one as it blends into the black.Looks like it is a lighter shade of blue also, I am not a bright colored persongood luck on either one they are both just as well done just different shading techniquesgood job
