Hi!
I like Entry #31/ nevertheless I am not totally convinced by the letter l and d. it looks a bit strange, can you try an other design for l and d bu same logo general shape?
I also like #36 #37 ! If you have any furtehr idea with the same style, dont hesitate to poste them (a bit different shape or new color)
I got the simplicity and sober style we are expecting ;-)
