Great first draft. Not everyone can recreate something like that. Bias tape is always a pain ( I desperately try to avoid it).
. Also I like to use muslin or a piece of horrible fabric I won't use for anything else when I make a new pattern. That way you can rip out seams and make tucks or adjustments without worrying about ruining anything.
All in all, you did great and I bet you'll be even happier with the next edition.
. Looking forward to seeing it!
