In Entry #1 I like the positive happy sense of color and design. Entry #2 is more linear and may work with the header layout best, wish the emblem could be a little larger.
#5 I like a lot. the linear design is easy to use. The color scheme is good. #6 and #7 The light bulb is a good idea but is not as exciting as #1,#2,and #5.
#22 is more abstract with a good play on color, The font is not as exciting to me. It seems too big and blockish. Thank you so much for your hard work on these.
