As far as her setup goes you should put an actual plant in there or two if you can make them fit. Also I would add more climbing things. On amazon they have moss sticks that you can tie wrap together or stick into the cage vertically and horizontally. You could also by some of those fake vines at petco and snake them all around the cage and hold them together with tie wraps. Baby chameleons especially like to feel like they aren't always being observed so the more places she's able to hide the better.
In my personal experience I feel as if my chameleon is able to be handled so well because I heavily planted his cage and such so he knew there was at least one place he could go where he couldn't be completely hidden etc.
As far as healthy looking she looks pretty good. I'm not an expert so hopefully someone else will chime in. However she seems to have one eye that looks darker than the other. Is that normal?
