How to write an Exhibition Review

I have never written a exhibition review quite as long or as formal as this one before so decided to research some tips of how to write one. I have read other reviews such as the ones in source magazine and although they give you some idea I felt some more structure would be helpful.

1. Discuss the artwork that stands out most to you from the exhibition and why you like it/don't like it
2. Try to find interviews to back up what you want to say about the artist
3. Find out about the gallery at which the exhibition is being held as a lot of galleries only display certain types of work.
4. what issue is the artist trying to portray in their work? what makes it uniique
5. Make sure to write in 3rd person
6. Opinions need to be backed up with evidence
7. Magazine layout ? A title that engages reader ?
