It's really difficult to comment when one doesn't know the family dynamics of a situation. Unfortunately, it is what it is and there's not much we can do about it.
That is a beautiful quilt, you did a great job and you should be proud of yourself. Now move on to something else, make a bedspread for yourself, or a wall hanging, or something really challenging like a mini quilt.
And if it's something your dad would appreciate more, trade your quilt for a nice dinner out with you (or whatever), and take your quilt and put it on display in your home so you can enjoy it.
