Thanks for the effort. I like the design element in #5 the best, but the text and color of #1. I'm also not sure why the little barbs on all of the rectangles. They sort of make this look like comment boxes.
I should say that I like the inclusion of color in the text of #1, but not necessarily the color blue. I like the colors in #3 and #5. I also like the text size in #3 a little better than anything else. Maybe the 'Babel' should be halfway between #3 and #1?
I still don't care for the barbs at the bottom of the boxes. A consultant in our case is not just someone who gives advice but does the actual work of putting together the network, security solution, whatever.
1) The rectangles could use some more visual interest. I'm not sure how best to get it. More radical perspective? internal color gradients? I wish I could be more specific
2) The artwork seems disconnected from the text. Is there anyway to associate them more closely, either by spacing or by color?
3) I'd like to see what the text looks like with a more visually interesting font.
