akimdave,
Welcome to the contest, and thanks for the great entries. You've clearly read the contest brief, as your logos clearly meet the design specs. I like
#18 more than
#17, but it may just be because of the size (I see that there is a design element of the x axis being longer in
#17, but my brain has a tough time comparing that vs. the shorter one because the only thing my brain is screaming out to me is that 18 is better because it is bigger).
I don't love the shade of purple of the bar chart. I think the bolder colors of my current top rated choice is the only reason yours is not in the top spot right now. Some experimentation on the bar chart colors could really help your ranking.
Another thought -- I wonder if the x axis of the chart could be extended all the way to the word "In". If it were, the x-axis could become the bottom of a rectangle around the word "In". Your design would then be the first to incorporate a design element with the word "In" actually "In" something. Having a design element for the word "Analytics" AND a design element for the word "In" would be really impressive.
Thanks again for your great designs,
Phil
