Here are two versions of the Galaxy-class bridge, based on a variety of sources. The design of the Enterprise-D bridge evolved over time, with many subtle changes from season to season, even from episode to episode (see this article on Ex Astris Scientia for an in-depth look).

The first design is close to the TNG Season 7 bridge of the Enterprise-D.

The second design includes two side stations added in the Star Trek Generations bridge.
