Thanks all! Here's what I think:
#14--You took my comments and implemented what I asked for--thank you. There's still something about the font, though. My favorite font/typeface style is still on #8. Perhaps remove the space between the two words (InsightQuality)? Also, the font has slight serifs--especially on the s, t, n, h, and y. I'm not a fan of serif fonts, so perhaps change the font slightly so it's round and completely sans serif. I liked that you tried to make the font heavier in #15, but I'd like both words to be the same font, but perhaps Insight is weighted/bolded more than the word Quality? In #15, it looks as if the two words are designed in different fonts (Quality looks more 'squished' than the more round 'Insight'). I also like the slightly smaller tagline in #14 over #15. Thanks--it's looking good!
#16--Thanks for you submission! I like the lowercase 'i' in the word 'insight' and how you removed the space between the two words. I also like how you weighted the word 'insight' more heavily than the word 'quality'. Perhaps the tagline could be smaller? I'm not sure if I like the gradient shading under the IQ (however, just so you know, I had another person take a look at the entries so far and he said that he liked this logo the best out of all of them).
I was just thinking about some other ideas, too, for the IQ image. Perhaps the part of the Q that it makes it a Q instead of an O (the ascender, I think it's called?) could be folded up glasses hanging off of the Q (basically, the combo of the letter O and the glasses would form the letter Q). I say this because the image could still incorporate glasses, but there wouldn't be a 'personification' in the image. Someone I showed the logos to liked the glasses, but didn't like how the letter 'i' was a person. Just a thought.
Please keep the ideas coming!
