My tips:
1. get a t-stat and get those heat sources regulated immediately. Hot spots for my snakes are about 88.5 with ambient being about 79.
2. Hes an adult male and could be off feed because of the season.
3. Fresh clean water should be available at all times.
4. Get hides that he fits in and covers his whole body without any kind of exposure. Reptile Basics has hides of many sizes that work really well.
5. Maybe cut back on handling a bit to give him some peace and quiet.
6. Try offering live feeders.
7. Humidity is a bit high.
