The creative input of the artist and the meaning behind what was created is as important as the elements of art. describe how the artist has used proportion and composition in this piece. in your opinion, what was the artist trying to convey to the observer?

Their points of view. Artists will go far to prove their points by using symbolism, poetry, all that good stuff. Like this for Example: you see an overly exaggerated crow in a small cage. The artist is conveying he/she is  stuck in a boring life with a lot of rules (An edgy dude would make something like that). Something like that, I guess. 

Hope this helps!
