Both pictures show show people who are performing.

There are people listening to the music in both photographs.

In one respect the pictures are quite similar because people are performing and being listened to by an audience.

The top picture shows a man playing a piano while the bottom picture shows a group of people playing in an orchestra.

In one photo there are some beautiful snow-covered mountains, trees and a lake while in the other photo there is an old castle.

In the picture above it looks as if some people are backpacking in nature while in the the photo below it looks like they are taking a short walk near an old castle. 

This one shows a cold, northern country like Canada but that one looks like it was taken in the United Kingdom.

One difference between the pictures is that we can see a lake and mountains in the one on top.

The biggest difference between them is that this one has a castle in it but the other one doesn't have any man-made structures.

This one looks more fun than that.

Taking a short walk in the country side isn't as tiring as taking a hike in the mountains with backpacks.
