Could someone me with these questions for art? i've answered them but i'm not quite sure.

1 looks correct,

for two I would put the white bricks and perhaps the water since it does not add to the subject

3 should be the light blue background

Explanation:

what can help is to think of a grayscale tattoo

the skin they leave empty or blank is negative space, but the actual linework contributes to the subject

negative space allows the image to feel balanced

soft,hard and rough for soft would be a pillow or a stuffed animal hard wood floor or a table rough paint
