really

"Really" means "very" but is better for casual conversation. "Very" is correct in written English, but can sound a little formal and old-fashioned in spoken conversation.

I thought it was a really original take on the story.

Also, "very" can only be used to modify an adjective: 

It's very small.

I'm very tired.

"Really" can be used for adjectives as well as verbs:

It's really small.

I'm really tired.

I really wanted to go

Do you really think so?

a vibrant (something)

Something that is "vibrant" is exciting and energetic:

• "Vibrant" colors are bright and strong.
• A "vibrant community" has a lot of interesting activities going on all the time.

an art scene

A city's "art scene" is all of the art shows, galleries, events, artists, art buyers, and so on that happen there. A "scene" includes both the events and the people. It centers around a particular city or neighborhood, and also a certain period of time.

In addition to "the art scene", here are some other kinds of "scenes":

the 1980's San Francisco punk rock scene

the club scene in Miami

the New York fashion scene

People who belong to a scene tend to talk, dress, and act alike. Some people fit in really well within the scene. These people can be called "scenesters", although that's a little bit of a negative term.
