I think the front looks pretty awesome, who cares about the back?
Personally I do not do a perfect 1/4in seam allowance, I move my needle to the right a number of clicks, found that thread and pressing takes up some of the allowance. It works for me.
Quilting friends don't point out flaws, LOL ... I would never do that to a friend, been there done that myself and it does just take practice to get points to match etc. Don't forget to get those seams to hug up to each other so that they meet.
