#72 is the concept we like best after further review. We love the silver and blue that you used, i am not fully sold on the halo above and below, do you have any other ideas that might add some texture above and below? or maybe a little different shape?
we really like #81 pickaxe incorporated. we also liked the over and under arches on 73 and 74. is there a way to incorporate these two elements into the #81 (and maybe something else above and below) to see how complicated it looks.
