Learning to sew: My hand-picked centered side zipper.

And here it is, in all its puckered, flawed glory. I'm not really sure why it does that. Perhaps I stretched the fabric? Perhaps I pulled the thread too vigorously as I sewed?

Also, you'll notice the zipper gaps a bit in some places. And then there's the top of the zipper. Pass those Puffs, please. I worked hard on this zipper. Hours and hours. I won't cry. It is, after all, my first side zipper. At least it opens and shuts with no problems.

Should I rip it out? Or try to improve next time? Do, please, share any tips to make this ? and my next side zipper ? look more professional. I beg you.
