[1.14.3] New PlayerRenderer / BipedModel

I'm are new in modding, so is being hard to know what I need to reach to my custom render.

Supposing that I start the mod now in the 1.14.3 (Forge 27025), and already canceled the player render.

Main Mod Class:

	public SorenMod() {

		FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
		MinecraftForge.EVENT_BUS.register(new PlayerManage());

	}

public class PlayerManage {

	  @SubscribeEvent 
	  public void renderPlayerPre(RenderPlayerEvent.Pre event) {
		  event.setCanceled(true);
		  System.out.println("-- Cancel Model! --"); 	
	  }
}

What classes I need to extend to customize and where and how I say to mod execute/fire that?
