opjose is so right on with his comment that nobody will notice. I also understand that you know that you can improve on it next time.

Enquiring minds ...

Looking at MinnFlyer's picture it appears that he (Mike) attached the fin side covering to the trailing edge 1st, thus establishing a nice straight anchor for stretching the film at the leading edge. This would have been done by tacking at the bottom of the fin at the trailing edge and pulling it taught vertically to the fin tip at the trailing edge. The open covering along the trailing edge would then be tacked at the center, then each remaining open half tacked in the center, repeating until the entire trailing edge covering was attached to the fin's trailing edge. Run your iron over the completed trailing edge. This would give him a solid anchor for pulling the covering straight forward to the leading edge. Then using the excess at the "cursed curve" at the bottom of the leading edge pull, heat to stretching point and wrapping the covering around the leading edge.

Forgive the poor use of tense in the previous paragraph but it ain't worth retyping

Your next effort will be easier I'm sure. Maybe it will meet your expectations - maybe not. Keep working on your stretching techniques and you'll be the one teaching others.

Good luck - looking forward to seeing the rest of your covering job.
