Style points are award when you do something fancy in the game, a few examples are Long Shot, it's worth 25k, Extremslide worth 50K and orange attack worth 50K, these are just a few examples the easist way to get 75K is to get two extrem slides in on shot resulting in 100K
Level 1-5(level with a U in it) aim just where the top two blocks of the U meet on either side. and you should get your first extrem slide half way down for the first and the second is just at the top of the u.
