#27 I like the concept - thank you for your submission - I just feel the font is too narrow. Perhaps try a more stylish font like Georgia for the Impact Unlimited to give it a classic look and feel. Then for the mark, try working with Georgia for the U perhaps and maybe place it and the dot within a circle in the same colour as the square you've used - to emphasise connectivity... thanks.
#33 #32 #31 - I thought Georgia would work, however, I don't believe it presents what I'm after. Thanks for producing them, though...Also, in seeing all 4 of your designs, I don't think the background square should be included.
