Thank you! We really love the creativity of finding the envelopes in the letters. We prefer highlighting the "E" over the "K", although we think #42 does a nice job of incorporating the "K" as best as it can be. We'd like to see variations of #43. Our biggest concern is that the "E" right now looks bigger than the other letters so we'd like to see what it looks like for the "E" to be more proportional. Otherwise feel free to play with colors. Thanks very much, really nice idea!
