He's beautiful and you built an attractive viv. I would watch his behavior over time, as I suspect he'll find that space a little too confining. If you see that he spends a lot of time pawing at the walls or the front that's a sign that he is frustrated and needs more room. Sometimes chams paw at glass panels because they don't understand why they can't get past it to the room they can see from inside. Not all of them do this, but if he does, you'll need to make more adjustments or expand his territory.
