Definitely luxe compared to a cup! I would suggest maybe some more decor around the edges or some mesh on one or two sides? My hierodula has some trouble climbing up straight glass so it would help him get back to the top easier if he happens to fall or jump. If nothing's really touching the ceiling and nothing is within arms reach to use to climb up or down he will probably just sit on the ceiling all day without knowing there's a whole world below. I glued some silk flowers to the top of my habitat so my mantis has something interesting to hang off or hide behind without climbing down, that could be a good way to add "more" without cluttering.
