How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:

package com.FireDude123.BOTW.entity.renderer;


import com.mojang.blaze3d.vertex.PoseStack;
import net.minecraft.client.player.AbstractClientPlayer;
import net.minecraft.client.renderer.MultiBufferSource;
import net.minecraft.client.renderer.entity.player.PlayerRenderer;
import net.minecraft.client.renderer.entity.EntityRendererProvider;
import net.minecraftforge.client.event.RenderPlayerEvent;
import net.minecraftforge.common.MinecraftForge;


public class PoseablePlayerRenderer extends PlayerRenderer {
    public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) {
        super(ctx, slim);
        System.out.println("here too");
    }

    @Override
    public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) {
        System.out.println("didnt get here lol");
        model.leftArm.xRot=(float)Math.toRadians(160);
        super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_);
    }
}

As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:

@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)
    public static class ClientModEvents
    {
        @SubscribeEvent
        public static void onClientSetup(FMLClientSetupEvent event)
        {
			EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true));
            EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new);
            EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new);
            EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new);
            EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new);
        }

        @SubscribeEvent
        public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) {
            event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer);
        }
    }

(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)

This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?
