#1 - i like the puzzle reference...i frequently tell people i solve puzzles... i don't like the way the LC looks. not sure if it is the font or the letters. #2 - nice, but too much of a boat/smiley face thing going on. #3 - maybe try the swirly as a stylized LC? #4 - looks too much like a fence
I apologies for the delay but had urgent health issues to solve (everything is just fine now) and I uploaded few new updates for you. Hope you love them and leave me your feedback.
