This is actually from Kenichi Sonoda's work prior to Gunsmith Cats, Riding Bean.
The main difference is Irene "Rally" Vincent being a blonde and partnered up with Bean Bandit. Where as in Gunsmith Cats, she was changed to a more Indian/English mixture and given a darker skin color and hair as a result. She is also not partnered up with Bean Bandit, although their paths intersect at times.
