i like your #59. it appears a little bit as it would be a tilted wine glass. Maybe you can bend some edges so that shape is a little bit clearer with the concept of a tlted glass and still keeping the letter K shape.
# 63, i see you understand the concept of what i wanted to say, but i would like it to still look like #59, so keep the separation between the gray of the "K" and the red color shape. Also keep the same shape of the red part like the #59
