What art 1

1- The mood of the images is more of a relaxed and subtle mood. In the first picture the girls face seems uninterested or unfazed. Her posture looks like she is tired or annoyed.The second picture she looks frustrated and her posture shows discomfort.

2- Oil paint

3-Color sometimes play as the emotion within the painting or sometimes tries to capture an inner meaning behind it. The red background gives an angry or hot vibe. 

4- I think the artist was trying to show two different women with the same general idea of the picture giving off two totally different emotions. The theme of the pictures was definitely capturing the emotions using a red background. I think the artists successfully captured two different moods in a same general picture.
