Personal difinition of art 2 to 3 sentences

Depends

Explanation:

I feel like this should be close to your heart but here is the google  definition of art:

the expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture, producing works to be appreciated primarily for their beauty or emotional power.

So basically you could say something on the line of "a visual expression of emotion, creating what your feel or think, using your creativity to demonstrate your thoughts."
