The motorcycle models look like fort condor's, very low quality compared to field's, but i think recoloring cloud could be a good first step, then the only model missing will be the snowboard, i remember that the very first sephiroth patch ( for pc) wasnt able to located the snowboard field model too, thats sad because i think thats the best mini game in GS
Have u tried to swap cloud's model with the shinra's soldier from the minigame? and recolored the armor in black and silver, i think that could be more realistic than a recolored cloud, so we wont see cloud's haircut
