Firstly, this all seems a bit odd to ne! The agency let him see you for free?! wow! not my understanding of the general attitude of agencies, but hey ho! As long as you got paid!
So taking it completely on the level, I think the guy probably was spot on! You probably were a little awkward and 'scripted' at first - who wouldn't be?
So I think he had a bad way of saying 'you were a little nervous initially, but 'relaxed' into it. For a first timer, that makes you stupendously 'good'. Thank-you my lovely - nay I kiss your tootsies and give you a huge tip?'
That is obviously what he meant! xx
Or he sounds like a 'type' of punter, I think we are all acquainted with - Young, fit, and in love with what he thinks he is and too 'busy' to pull girls as they always want him to marry then'
If you say so Darling - Yawn! xx
