Writing a description may be difficult for some students, what I've seen in my experience is that they get lost. So I've found useful to give them the steps they have to follow aswell as the order of the different aspects they have to write about. You'll find also some vocabulary and writing expressions that can help your students to write it right! Also it is a good way to practice the Passive voice.
I hope you find this useful as I did..good luck!!
