I am making a simple board game. In the game there is a fixed background called myTexture and others are textureGoat and textureTiger whicha are to be placed on top of the background(myTexture). But i am having problem that fourth and fifth component is not displaying however, the sixth component( i.e. myTexture) is appearing. Here is my code, please look at it

    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.Green);

        // TODO: Add your drawing code here
        spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend);

        //placing tiger
        spriteBatch.Draw(textureTiger, new Rectangle(22, 25, 50, 50), Color.White);//first component
        spriteBatch.Draw(textureTiger, new Rectangle(22, 407, 50, 50), Color.White);//second component


        spriteBatch.Draw(textureTiger, new Rectangle(422, 25, 50, 50), Color.White);//third component
        spriteBatch.Draw(textureTiger, new Rectangle(422, 407, 50, 50), Color.White);//fourth component


        //placing goat
        spriteBatch.Draw(textureGoat, new Rectangle(125, 110, 50, 50), Color.White);//fifth component

        //placing background
        spriteBatch.Draw(myTexture, new Rectangle(0, 0, 500, 500), Color.White);//sixth component

        spriteBatch.End();
        base.Draw(gameTime);
    }
