Fun fact: I've never painted a hover-bike chase. WHY?
Little genre trope tidbits: the good guy is on the right because #1. he just served a plate full of foot to the dude on the left #2. his bike is scrappy and worn (sci fi fans have been taught to be suspicious of anything too smooth and perfect) #3. he's got a cape, which gives him a little personality other than 'random helmet man.' I'd fit a dog in there if I could, just to make sure you knew he was endearing. But a kick to the face will have to do.
