Entry #4 is the most interesting of your 4 entries. I like the Executive on top of the word Coaching. I like the globe in Coaching. I like Clear Results called out. The only element that I am not sure of is the X turned into a person. I have seen that done with other programs using the word executive.
Entry #3 would be interesting without the X looking like a person. I like the line at the top. It looks more streamlined than #4 and I wonder if removing the person image in the X in #4 would help that one. Or maybe there is another design that combines the best of these two?
