Hello, Olivia! I'm happy to see your diary once again. Here are the corrections I made for you tonight...

    ***********CORRECTED DIARY OF OLIVIA PARK************

My dream is to be an artist. I will do hand paintings, water color, and fantasy pictures. I want to be an artist because I love art and I am good at it. I love to draw princesses.

    *********************************************************

OLIVIA: My dream is to be a artist.
CORRECT: My dream is to be an artist.

EXPLANATION:

Olivia, don't forget that A is used if the next word starts with a consonant sound (B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z). AN is used if the next word starts with a vowel sound (A, E, I, O, U).
_____________

OLIVIA: I wil do hand paintigs,water color,and fantasy pictures.
CORRECT: I will do hand paintings, water color, and fantasy pictures.

EXPLANATION:

Please be careful with the spelling. Please recheck it before submitting. ^^ <will> <paintings>
______________

OLIVIA: I want to be a artist because I love art and I am good at art.
CORRECT: I want to be an artist because I love art and I am good at it.

EXPLANATION:

Again, Olivia! Please use AN if the next word starts with a vowel sound.

Let's use the pronoun IT instead of repeating the noun ART to avoid redundancy.
