Cool designs, thank you!
Entry 5 is a favorite, definitely keep this one in blue, but would like to see a couple color comparisons (red, then green). Like the bold and then normal font. Would like to see a comparison with small caps? What font is this?
Love the double arrow design that looks like a fast forward button. Could we see a flat design? Without the 3D effect (thinking about how that would look on a business card, not sure if the 3D effect would be notice-able on a biz card). 3D effect would look great on the web.
Entry 2 and 5 (and others): like the design but not the colors, avoid purple and orange.
Overall, very cool designs!
