Not bad for a first time 
but maybe center the text: Dr. Norman Borlaug, third from the left, trains biologists in Mexico on how to increase wheat yields - part of his life-long war on hunger.
a little more
I think its centered little bit more now thanks 
While it looks okay @Dashi it’s too much like the sample page. The sample page is just that, a sample.
The instructions say to build an app that functionally similar to the sample and to give it your own style.
Start with a blank page and think of someone or something you’d like to tribute and go from there.
Good luck!
Oh, thank you so much i understood different . My bad , next will be my own .
