Yes a lil bit of plants or something to clutter the cage up a lil more would help your ball feel a lil more secure. I suggest getting a digital thermometer and hygrometer. You can get one that is a combo that reads both , it comes with a probe you bury the wire under the aspen shavings and put the probe under the hot spot . This will give you the exact temp on ground level of the warm side of the enclosure. You also need to have a slightly cooler side for the snake to go to if it's feeling the need to cool down. I couldn't see the lighting in the pic but only one heat lamp is usually necessary, and put it on one end of the cage. The problem with the thermometer hygrometer that came with it is that a lot of them are not very accurate and after time the can wear out and give false readings.
