Photographic review

If I were a judge, I'm afraid you would be very sad.

River series:

I can't see what I want to show. If it's a building in the background, then the trees in front are annoying. If it is a river, then the proportion of the river is too small. And the sign in front.

The composition is messy and the main body is not prominent enough.

Automobile series:

Change the name. I can't see any cars. The composition of car 2 is ok. Is the front sign the main body? If yes, please use telephoto to make the background cleaner; If not, then change the position and throw the sign out.

Fire protection series:

If you don't look at the name, I think you want to show the depth of the corridor. ...

Don't use flash, it will cause damage to the environment.

Summary: There is nothing wrong with being a travel companion. If we say it's a "work", I'm afraid it's something that was shot casually without careful consideration.

Suggestion: Make the subject clear first, look at more photos and change the perspective.
