I'm not sure which symbol I like most but they're all pretty sweet. What I find particularly striking though is the typeface; it looks so nice and sharp. With the softer color tone it gives the logo a fresh and modern look.
Is this the website of the agency you did this logo for? If so they made a terrible choice. If not, I'm very curious what the winning design was because your work is striking.
Thanks for the great comment! Good you like the typo, I saw on your profile that you're particularly experienced when it comes to fonts(and you're doing a great job!) And yes, that's the website. The winning work was a surprise for many people
It's quite ironic to me how a website for crowd sourcing logos and such doesn't know what's good for their own brand. This Mintia branding [the one they chose] is almost as neutral as possible, which is no good for a brand.
