I like both of these very much... I wonder if there's a way to add more detail to the cityscape, to make it more obvious that it is a cityscape... I knew what the shapes represented because I requested them, but I'm not sure that others would immediately get it.
I really like the addition of the "lights" over the billboard in #6. Can we create some white space in the billboard itself in 6, or is it too small (similar to number 1 or 2)?
I looked at your portfolio and I love the stuff you've done. Perhaps I've given too much direction. I love Jamey Cox Realty, Ember, Ready Set Boom, and your personal logo... feel free to make up whatever you like, without regard to my instructions.
All you need to know is that this is an inspirational speech and book, and you may want to check out www.DarrenKavinoky.com and read the Keynote page and my bio page for more info. Use your imagination, and I'd love to see what you come up with.
