I'll give you kudos. This could have been executed in a way that would have been considered overblown and pretty cringe inducing.
However, the style you and your Father illustrated not only looks very period correct (hand-brushed vaguely anime aesthetic for the pin-up, paired with a good balance of period sponsor graphics). The livery is also pretty tasteful in the ratio of risque to legit racing livery.
Really unique and obviously some thought and consideration that went into the design. I definitely appreciate your creativity bringing it to life.
