I believe she used the autofocus on this? Which in, in my guess why the focus is off. The obvious object that she wanted to show, isn't in focus, instead the cup is. I'm not sure if you can manually adjust the focus after AF has kicked in like I can do with AF-S lenses from Nikon, but tell her to rock the MF ring
Otherwise, in the compositional aspect, it seems a bit "dull", I mean, we see this aspect of moths every day. Next time she sees a moth, or you see one, maybe try to get underneath it, or ahead of it to get a more dynamic view.
Also, crank open the aperature to get smaller DOF, would help to blur out the background bucket/cup, thinger.
