These have strong potential. I'd like to see warmer, more vibrant colors. I also think the stroke weight is too heavy. The spring element attached to the "g" is a nice touch. I think it's not quite there in terms of personality and simplicity, but I like the direction you're going. I also wouldn't mind seeing this in a few different typefaces, though I think you're in the right ballpark with regards to typography.
This is a nice step forward in #10. I'm still not quite feeling the typeface. The type in #2 might be closer as it's slightly bolder (though I'm not a fan of the heavy stroke weight). I do like the treatment of the coiled "g" in #10. It's more distinctive and simple than its counterpart in #2. Your choice of color makes me wonder if I properly described what we're after. Entry #12 is closer to what we want ... bold and warmer (though even #1 doesn't quite have the shade of blue quite right). I think you're making some interesting inroads with your entries. They just need to be rolled into one and iterated a few times.
#57 has real promise. The typeface is not quite right ... looks too dated, almost '70s-like. And while I really like the pie chart embedded in the "g," the additional spring treatment on the descender is too much. Can you try this one again with a more modern font and without the squiggly descender on the g? The typeface in #56 is probably closer to what we're after.
