Internship Question - Change up email?

Hello, Question for all you that have secured summer stints, or to those that have years experience in IBD.... I emailed an MD of a Mid Western Boutique for an internship. He said he wasnt sure if office was taking interns this year, basically told me to email him back and we could asses the situation. I sent him a template email very similar to the one found in the networking guide. The question is hen I follow up with him, should I send the same exact email or try and change it up?

Any and all advice is welcomed :)
