Well done!! My boy still rarely comes out on his own. He despises me. Ive had him for a year on the 6th
Just go at his pace and your boy should warm up just fine. Every veiled (any chameleon for that matter) is different though.
Having a trusting chameleon makes vet visits, general inspection, and cage cleans, (anything requiring their removal from the enclosure) a lot easier and less stressful for both you and him.
