I like how a number of our theme elements are used in #3 & #7, but am not a big fan of abstract stick figures.
Can you take a look at the color palette from our primary logo found here: http://lifedevelopmentinstitute.org/, and see what you might come up with?
For the final design, we also request two versions from the finalists – one for white background and one for dark background, so that I can overlay more easily a dark background version on top of a photo for banner promotions, etc.
