thanks for the designs; I like the text on #49-50 - the image on these though is a little bit ghostlike. We would love to see similar ideas from you though on this theme.
#51 - clever use of the K informing the person. I think this one is a little bit severe looking though. Perhaps you could try bringing the icon and the text onto the same line or other variations that come to your mind?
I like the simplicity and clean this of your designs. I'd love to see a slightly more synthesized look -- where the image and the text flow tightly with eachother
