I dont know if you need two locks. I think just one with a check box works. I don't love the yellow where it is.. maybe with this better to do a dark blue where the purple is and a nice light blue (glowing) where the yelloow is. Love the simplicity.
#47 I find very very interesting. Don't like the purple shade in the middle. I love the twoshades of purple in the name. I guess it feels kind of "sporty" to me which I don't think is the right genre. Overall I like the house and checkmark and font/font coloring.
#63 I feel like we need arrows in two directions. #56.. wouldn't mind two arrows on the top and bottom of that circle where you have the blue and yellow bands.. perhaps make those into arrows.
