Custom Item Projectile Rendering Trouble

I am having trouble with rendering my custom projectile. This is my first time using client and common proxies, so my apologies for my lack of skill.  

Main Class
  
  @SidedProxy(clientSide = "mymod.ClientProxy", serverSide = "mymod.CommonProxy")
		public static CommonProxy proxy;
	

		@EventHandler
		public void Load(FMLPreInitializationEvent Event) {
		proxy.registerRenderThings();
		}



Delcare
  
  	        public static Item RainbowSword_1;

Load
    
    RainbowSword_1 = new RainbowSword(20721, REDSTONE, "rainbowsword");
    GameRegistry.registerItem(RainbowSword_1, "RaibowSword");
    LanguageRegistry.addName(RainbowSword_1, "Rainbow Sword");

package mymod;

import mymod.entities.ExplosiveArrowRender;
import mymod.entities.MyExplodingArrows;
import mymod.entities.Rainbow;
import mymod.entities.RenderRainbow;
import mymod.items.RainbowSword;
import net.minecraft.client.renderer.entity.RenderSnowball;
import net.minecraft.item.Item;
import cpw.mods.fml.client.registry.RenderingRegistry;
import cpw.mods.fml.common.registry.EntityRegistry;



public class ClientProxy extends CommonProxy{

	
@Override
public void registerRenderThings(){

	 
	
	RenderingRegistry.registerEntityRenderingHandler(Rainbow.class, new RenderRainbow(Main.RainbowSword_1));
	    RenderingRegistry.registerEntityRenderingHandler(MyExplodingArrows.class, new ExplosiveArrowRender());
        
System.out.println("Random Mod: ClientProxy loaded");



}

}
