Answer: I can't see the picture but I think that all you have to do is think about what your presentation is about.
Explanation:
If you are trying to make it match what you are doing for your presentation then all you need to do is to go and pick something that matches what you are working on. Just pick what you think is the best thing for that picture. I think that if you know what you want then just go with what you think is the best thing to choose.
