I don't know a polite way to say this so I'll be blunt. The first words out of mouth were "holy crap" at how bad the art is. The big image in the link and on the kickstarter video look like mediocre high school art. It's really bad. The game interface is then pure programmer art. Please, please, please hire multiple artists.
That said, this is a great market to be in as HEX raised 2.2 million. Their project already had significant investment before hitting kickstarter though. The bar is quite high. http://www.kickstarter.com/projects/cze/hex-mmo-trading-card...
