I like both concepts #48 & #49 - they are both very good. i really like the puzzle idea too. i would like to see how else the words could be laid out i guess and what other colour variations could work?
Sorry, I was made to withdraw some entries and change them to others, becouse one of the designers thought one small detail of the logo was similar to mine. Also I made some colors and font changes as you asked me. If you need any more changes just write me.
