2 and 3 are hard to read. As they stand right now, I like 4 the best, but it is inaccurate. Change to evolution and it will be good. 1 is just waaaay to busy. Hard to handle all the pics at once and it seems cluttered.
Number 3 would be the best if the text was made to be a little easier to read. Lightened up a bit or something.
