The results are quite consistent, as in you can distinguish one trick from another, but no two tricks of the same type ( kickflips for example) look the same. Little things like the way the skater was leaning, or the curve on approach, all make for different end reults.
The same trick from two different skaters look similar, but have great variances..
Some skaters have been lightfooted, and it shows in the paint, some skaters have been more dynamic, hence more dynamic results.
That coupled with the skaters choice of colours and trick types has made for quite a broad range of canvasses.
