Lovely pics, thanks for sharing.
Couple of points: are you feeding mixed lettuce leaves there? Lettuce is really not the best salad for Bearded Dragons, not least because it has so little nutritional value. If you want advice on veggies that are better for regular feeding for Bearded Dragons let us know and one of us can point you in the direction of a nutritional chart.
Secondly, the tank you have him in is fine for him as an adult - if you were ever to buy him a mate and house them together you would need something larger.
I hope this helps and you have a lovely Bearded Dragon
