I think it is very cool that you chose to go for a copywriting internship as an Art Director! I think it is brave that you chose to improve your writing skills with this experience. I know from my stand point as a fellow Art Director, copy is super difficult for me to understand, it is not how my brain works and I feel if you can understand both you are a much better candidate for any position. I need to work on my own skills as a writer and really respect your path. I’ve been writing a lot of emails at my own internship and find that even writing those can be a struggle! I bet that this experience will help you so much when looking for a job! And since I am graduating at the same time I am sure we can support each other through the job hunt! Good Luck with everything looking forward to seeing you at graduation!
