Is this conscious action?

In the below video (8:28), a visitor at a zoo records an elephant paint a picture, apparently a self-portrait of elephant with flower.



This begs the question to me: is the elephant aware of what she is painting? She definitely is deliberate about her actions, it's not just a case of putting random splotches on a paper that humans then interpret as a picture. But the question is whether she understands that it's a drawing of an elephant, or if to her it's a random pattern of lines that she has learned produces praise from the audience and treats from her keepers. If we saw creativity (that is, variations of the picture), that might lean me towards thinking it's conscious action with understanding, but then again elephants are remarkable creatures and perhaps she is capable of memorizing dozens of patterns that result in rewards.

Paintings are not, in my opinion, reliable Turing tests for animal intelligence.
