Looks like you have already put it together, so I would say, no.......there isn't much you can do at this point.
The only thing you can do is cover it with a lot of frosting or whipped topping.
But if you leave it the way it is, I would try and make it look MORE lopsided and uneven.......as that is the style of some cakes nowadays...
Maybe get some little characters to put on the top and side of the cake that look like they are falling off of it or something.
Or decorate it with a lot of edible flowers, toys, and candies.
