Responses for ipad presentation

Many people said that my presentation is easy to understand but some of my classmates thought that I should explain about my country or my family more in my presentation. If I write the explanation in detail, my presentation will be better. Especially, I should add information in fourth slide. 

Some classmates said my presentation was good because there were many pictures and the pictures are funny but there were some students who thought that I should add some information by pictures more.

Also there were comments like "my presentation was quite simple because of the background picture." and "While I give a presentation, I should look at the audience."
