Art teachers know nothing. It's not a class you can grade, because the grade depends on your teacher's taste, not yours.
I say the amount of work you put into a work should be a major determinator for how good an art piece is. This obviously didn't take much, being a bunch of filters and it's not even your photo. Just selecting pixel-jumbling scripts from a menu in a particular sequence, in other words.
