Redesign of Zentao

Hey guys:
This is the my first work which used to get the dribbble invitation.It is a redesign of Zentao.
ZenTao is our company used to manage the project and product research and development of a system, but for ordinary users, interface information is too large, the key is not prominent, operation is not convenient, so I tyied to redesign, I hope you will like it, thank you.
