Very nice. Thank you for your submissions and thank you for including a version with the beta page's background.
We like both the speech bubble and check/box treatments. The box might be better in terms of suggesting the electronic nature of this survey service -- smart phone, monitor, tablet, etc. It is also very clean.
Thank you for the feedback and ranking! I am very happy to hear you like my concept so far. I will continue to work on it and submit new ideas as they come. Please let me know if there is anything specific you would like to see, I would be happy to make any changes. :)
Do you think that #5 would work with a larger/stronger/bolder checkmark? It pops pretty well with the white on dark version in #6 (but possibly could be bolder there too) but stands out less in the blue/orange version.
