I dislike the typography. Try more font styles / other fonts.
The event info looks too squeezed on the bottom. Give more space to “live”.
Try some text effects in your heading. Looks to simple.
The reviewer means the visual hierarchy of the typography. Here’s some info about that – http://www.freddesign.co.uk/2011/05/archive/good-typography-an-introduction-to-hierarchy/
You just need to improve the layout and typography on the design.
