Disturbing Crows in Wheatfield

I was astonished by how rushed Van goghs brushstrokes were in his last painting" Crows in Wheatfield." Van Goghs Crows in Wheatfield compared to Starry nights looks unfinshed like he meant to do more however couldn't. " Crows in Wheatfield," seems disturbing because of the crows and the weird looking wheat, compared to "Starry Night," which is peaceful and serene. Not to mention crows signify death as if he was planning his last painting like the crows of death were waiting for him.
