analog to PWM (for DC motor control) {need advice};

Hello.
This is a code I came up with to control a simple dc motor with an ps2 joystick potentiomiter. It works ok, but i would like to know how flawed it is or if there is a better code to use.
Thanks, Rob.

const int analogInPin = A0; 
const int motorFwdPin = 9;
const int motorRevPin = 10;

int sensorValue = 0; 
int motorFwd = 0;
int motorRev = 0;
int motorOff = 0;

void setup(){}

void loop(){
  
 sensorValue = analogRead(analogInPin); 
 motorFwd = map(sensorValue, 550, 0, 0, 255);
 motorRev = map(sensorValue, 480, 1023, 0, 255); 
 motorOff = map(sensorValue, 480, 550, 0, 0);
   if (sensorValue <= 480)
     {analogWrite(motorFwdPin, motorFwd);} 
   else if (sensorValue >= 550)
     {analogWrite(motorRevPin, motorRev);}  
   else {(sensorValue > 485 && sensorValue < 545);
     {analogWrite (motorRevPin, motorOff);
     analogWrite (motorFwdPin, motorOff);}}
    }

Looks pretty Reasonable.
