Yeah I do art in college.
When doing art research, what I normally do is include:
- The artist's biography,
- Maybe briefly write about what you think of their work but don't go into too much detail,
- Try to include a quote or two from the artist about their own work,
- Back this up with loads of pictures (you can never have too many examples of the artist's work!)
Finding quotes and giving your own opinion about their work may help to get you extra marks, but I don't think it is essential... it just looks good
What the people are looking for is mainly the biography and pictures.
Hope this helps!
