There are two main types of artists. Let's call them Billy and Bonnie for illustration purposes. Billy can draw anything he sees, but struggles with drawing from his imagination. Give Billy a piece of paper and a pencil, and he'll stare at it blankly. Hand Billy a photo to copy or a bowl of fruit to draw and he will fill that paper with every detail he sees. Bonnie, however, is ready to fill the paper with fantastic creatures before the pencil hits her hand. But if you hand her a photo to copy or a bowl of fruit to render, she will be immediately frustrated and it will take her twice the time it will take Billy. Are you a Billy, or a Bonnie?
