How would we more accurately translate 那胸前凸起的完美弧度 (published translation: "perfect curve of the convex in front of her chest")?
那修长的睫毛，
Those slender eyelashes,
那水润的眼眸，
those doe-like eyes,
那高挺的琼鼻，
that exquisite straight nose
那粉嫩的小嘴，
those tender pink lips,
那胸前凸起的完美弧度，
the perfect curve of her ample bosom,
再加上如雪一般的白皙肌肤，
also her snow-white skin,
真的是美到让人砰砰心跳，
really amount to beauty which makes my heart pound,
说其是仙子下凡也不为过。
it is not an overstatement to say, she really resembles an immortal descended to our world.

也不为过: not too much to say, not an overstatement

Must be a lady-boy from Bankok!
