At a year an a half she needs unlimited hay and 1/4 cup of pellets a day, which means you need to take the free feeder out. The wire bottom is really hard on their paws, and if she's litter trained there's no need to have it or the newspaper lining at all, you could cover it with cardboard or a piece of linoleum for a quick fix.
You should also get her spayed if she isn't already, unfortunately cancer in rabbits is pretty much a definite unless you do.
Does she have an extra pen to run around in or something? That cage is really too small for the bunny to be in.
She looks super sweet!
