I love this anthology! And I, personally, love the cover. And not simply for the reason I immediately loved it, as in, where did you find her, oh my god... But for the way she is posed, as if she is landing. It's perfect.
The fact that the muse is not on her pedestal has a particularly poetic verisimilitude, doesn't it? As if she has better things to do than stand around inspiring poets all day. Whether the picture captures her mounting or dismounting depends on how bad your case of writer's block is.
