Would it sound awkward if I say "first" instead of "initial" in this context?

You could say "first" instead of "initial" here since that's what it indicates here. It wouldn't sound awkward! "Initial" is just slightly more formal. Ex: My initial impression of you wasn't a positive one. = My first impression of you wasn't a positive one. Ex: Initially, I wasn't sure. But you convinced me otherwise. = At first, I wasn't sure. But you convinced me otherwise.
