The shawl looks great so far! Keep up the good work.
If you don't feel like buying more yarn to make it longer, you could simply use it as a scarf. I think that either way you use it, the shawl will look very nice.
"Who shall find a valiant woman? far and from the uttermost coasts is the price of her...she will render him good, and not evil, all the days of her life. She hath sought wool and flax, and hath wrought by the counsel of her hands...her fingers have taken hold of the spindle. Favor is deceitful and beauty is vain: the woman that feareth the Lord, she shall be praised." ~Proverbs 31
