I'd be delighted if my first efforts at piecing were half as good as yours!
In modern times our exposure to factory-produced goods has created an expectation for "perfection" that obliterates what is human and artistic. Rejecting that quilt you started would be akin to refusing to eat Mom's apple pie because the crust is sunk in on one side. Pies from the freezer in the grocery store might look more perfect. Which would you rather eat?
The only caution to consider before you put it together is check to see if any of your seams were too narrow to hold up. Those should be done over, of course, unless you just plan to hang it on the wall and never use it.
One more point, though: if you know in your heart that you'd be happier if you fixed it first, buy an inexpensive dog trimmer such as this for ripping seams.

Practice on a scrap sewn with the same kind of thread and stitch length. Clamp the end of your piece to the edge of a table or get someone to help because it's hard to do this with only two hands. Start the seam by pulling a few stitches the usual way, and then zzzzzzzzzzzip! You won't dread ripping seams nearly as much after you use this.
