Change bathroom light

[MD915]

I am living in a rental apartment and one of the lights in my bathroom has started flickering. I went to change it but had difficulties with it. I have tried to remove the bulb I'm having issues with removing it from the ceiling. I have tried pushing and twisting but it only moves a quarter turn anticlockwise before swinging back to its position. Any advice would be appreciated.

Thanks!

Those three little lugs on the inner circle are to help you rotate the inner circle/ring. Once you twist it, it will drop down with the bulb.
