Not bad at all. I would add a couple more vines with leaves and maybe another small plant on the bottom and you will be good to go. Is that a floresant UVB bulb? He should really have a tubular one. They had issues with those kind of bulbs harming reptiles. Their eyes for the most part. He also needs a basking bulb too. Any ballisk will do and any normal house bulbs should do. Try starting out at 40w and work your way up to achieve greater temps. Humidity for Jackson's needs to be pretty high 50-80% with time in between mistings to dry out a little bit. What kind of supplement is in the blue bottle? I can't tell from the photo. He will need plain calcium no d3 2-3 times a week. And I use reptivite multi vitimains with d3 1 time a month. Or you can use calcium with d once a month and multivitamin once a month. Feel free to ask any more questions you need too! There will be some here who can help out
