I think that the #3 could be an interesting direction, but could you try to use the down part of the maltese cross (no the real one... you would have to reshape one) to be the down part of the lock ?
#12 is nice but the black lock eats the logo (maybe find a way to put less black, to empty the inside or to put a more grey color) The problem with taking the exact maltese cross is that the lock has a strange lower part... maybe it would make sens to reshape a bit the 4 extremity of the cross
Thank you. The lock is still eating a little bit the logo because of it's darkness... could you please try with inside white for exemple... or with more grey color.
Sorry to insit but I really like #26 but the lock is still eating a little bit the logo because of it's darkness... could you please try with inside white for exemple... or with more grey color.
