Especially in longer works multiple viewpoints are used. I've been guilty of this a number of times and I like showing the story from many character's viewpoints. I once used this as a vehicle to do vanishing characters. A number of the characters were killed leaving only the heroine, the villain and the hero standing when the book ended. There are tricks to doing this.
One of the tricks is to take a bit longer to make the character come alive and for the reader to form a bond with them. Another trick is to perhaps show some of the characters in the opening scenes and how they relate to each other. This I used in the Affinities series, starting iwth one character and bringing her two brothers and sisters into her opening scene. The only character not there was the fifth character who became their friend.
Another trick is to have an event surrounding them like a fire that effects a number of people. This is called building connections and is very necessary.
Keeping the switches simple can help. Using them to advance the story is another way. Take time to let the reader know you'll be writing in a second character's view for a time. Referring to the next viewpoint character by name or wondering where they are located can be another way to alert the reader. Don't clutter the openign scene with too many characters in too short a time perion. Introduce them slowly rather than have a scene where there are a dozen characters vieing for the reader's attention.
Keep these scenes active. Static scenes don't do much for the reader/
So choose your method of choosing a viewpoint character or characters for a story with care.
