As an exercise, I created an illustration derived from a six word poem in only a few hours.
Retired Military,
Soldier Sleeps,
PTSD Awakens.
I first created the illustration in Adobe Illustrator to create the line work and fill in the mid-tones. After, I transferred the file to Adobe Photoshop to apply gradation to the mid-tones. To finish, I re-entered the file to Adobe Illustrator to apply the typography.
