1. I'm not crazy about the dot and little squares. It might be too simple without them so try something else. 2. I'm really starting to like the two color thing - the blue and floro green looks great.
Regarding #10: 1. Can you put it on a dark background so I can see what's going on with the "T" in IT 2. Can you put the periods in "IT" so it like "I.T.". I don't want people thinging it's the word it. 3. Can you make the top edge of the green square straight so the top of the "T" goes off the square and onto the background.
#14 1. Can you try the lighter font that you used on #10 2. Can you make the tagline green so it will show up on the dark background.
