Yeah, I thought that'd be the case, which is why I thought it would be a bad idea to place her on top of the text box.
Perhaps flip the image horizontally and then move her arm (this would be the one that isn't bent once the image is flipped) so that it's one the edge of the screen? You don't really need to see both of her wings because the player can infer what one wing looks like from seeing the other. I think that would look better, and it would give you much more room for the message text.
The wings are really the problem here, because the space below her right wing is just far too great IMO.
