Removing Backswing from spear

[SteakBites]

I'm trying to make a weapon that acts similarly to the starlight, the problem I'm having is the texture having backswing like a spear

how can I get rid of it

following is the code for the projectile, where I am to assume the problem lies

using Terraria.ID;
using Terraria;
using Terraria.ModLoader;
using Microsoft.Xna.Framework;
using System;

namespace MonsoonSais.Projectiles
{
    public class DystopiaProjectile : ModProjectile
    {
        public override void SetStaticDefaults()
        {
            DisplayName.SetDefault("Dystopia Projectile");
        }

        public override void SetDefaults()
        {
            Projectile.DamageType = DamageClass.Melee;
            Projectile.scale = 1.0f;
            Projectile.penetrate = -1;
            Projectile.aiStyle = 19;
            Projectile.width = 32;
            Projectile.height = 32;
            Projectile.friendly = true;
            Projectile.hostile = false;
            Projectile.timeLeft = 600;
            Projectile.light = 0.25f;
            Projectile.ignoreWater = false;
            Projectile.tileCollide = false;
            Projectile.ownerHitCheck = true;
            Projectile.hide = true;
        }

        public float movementFactor
        {
            get => Projectile.ai[0] - 0.3f;
            set => Projectile.ai[0] = value;
        }

        public override void AI()
        {
            Player player = Main.player[Projectile.owner];
            Vector2 ownerMountedCenter = player.RotatedRelativePoint(player.MountedCenter, true);

            Projectile.direction = player.direction;
            player.heldProj = Projectile.whoAmI;
            player.itemTime = player.itemAnimation;

            Projectile.position.X = (ownerMountedCenter.X) - (float)Projectile.width / 2;
            Projectile.position.Y = (ownerMountedCenter.Y) - (float)Projectile.height / 2;

            Projectile.ai[1] += 1f;

            if (!player.frozen)
            {
                if (movementFactor == 0)
                {
                    movementFactor = 1.3f;
                    Projectile.netUpdate = true;
                }
                if (player.itemAnimation < player.itemAnimationMax/3)
                {
                    movementFactor += 10f;
                } else
                {
                    movementFactor += 1.6f; //This is how fast the spear moves
                }
            }

            Projectile.position += Projectile.velocity * movementFactor;

            if (player.itemAnimation == 0)
            {
                Projectile.Kill();
            }

            Projectile.rotation = Projectile.velocity.ToRotation() + MathHelper.ToRadians(135f);

            if (Projectile.spriteDirection == 0)
            {
                Projectile.rotation -= MathHelper.ToRadians(90f);
            }

        }
    }
}
