It often depends on the type of art that the teacher was looking for. For example, if a ceramics teacher was looking for a coil pot, often times they will just hand out a rubric. Typically the requirements on art rubrics are loose- otherwise everybody's work would end up looking identical. For example, one requirement could just be "a couple rows of different coil designs" for a coil pot for full points on that assignment. Art teachers also grade based on a self-reflection form students may fill out. For more abstract pieces, the teacher might just grade based on why the student designed their artwork like that.
Hope that helped you.
        
             
        
        
        
Yes , a rough draft is a preview of brainstorming of thoughts and ideas you want to write about and how you can rewrite them better with proper grammar and organization.
        
             
        
        
        
Take EDM for example; it's a combination of words and sounds all cramed together to create a piece of music, most of the time it has no official reason or back story but is simply made to be enjoyed. This concept is the same with Jazz music. When jazz was invented there was no definitive reason or way to play it, you just grabbed an instrument and started playing whatever cords and rhythms you thought sounded nice.
 
        
             
        
        
        
<span>Artists tend not to use symmetrical balance in their artwork simply because, well, it's boring to look at. The eye is drawn to what one is not used to; therefore, asymmetrical balance, a focal point not in the center of the composition, exaggerated object size, and use of negative space rather than positive are all different ways an artist will use to create a good composition.</span>
