Besides the gravel issue the only other thing I see is that it looks like the stand is sagging in the middle. Maybe it's just the way the light is hitting the metal but if it is actually sagging I'd move the tank to the floor, you don't want to deal with the mess a broken tank leaves behind

.
You may want to consider a floating dock to give more swimming space for lola and because it's not ideal to have such an abrasive basking area as you have now, it can damage her shell.
Also, you'll notice that once the gravel is gone the water will stay much cleaner as less debris is trapped in areas the filter isn't strong enough to clean out.
Other than that it looks like you're off to a good start.
Lola's a cutie by the way.
