Here's why:
* Missing Verb: The sentence lacks a proper verb. "Look" is an imperative verb (a command), but it's not clear what action you want the listener to take. Do you want them to "look" at something or "look" for something?
* Informal Usage: "Got" is informal and often used in casual conversation. In more formal settings, "have" is a more appropriate verb.
Here are some grammatically correct alternatives:
* "Look at what you got!" (This emphasizes the act of looking)
* "See what you have!" (More formal, emphasizes possession)
* "You got this!" (Common phrase, expresses encouragement)
The best choice depends on the context and tone you want to convey.
