Awareness is always aware but attention implies directed awareness, so awareness isn't always attentive. You could say that attention is a subset of awareness.
The meme could go either way. The pink thing could be a specific piece of the white figure asserting dominance over the whole, or the pink thing could be "the whole" reminding the white figure that it is itself merely a subset. In this case either works. It's your call which makes more sense in this context.
