Display custom tooltip as Balloon

I am using a custom tooltip class in my WinForm application. It works great. But i would like to show it as a Balloon. Here is my code- 

class CustomToolTip : ToolTip
{
    public CustomToolTip()
    {
        this.OwnerDraw = true;
        this.Popup += new PopupEventHandler(this.OnPopup);
        this.Draw += new DrawToolTipEventHandler(this.OnDraw);
    }

    private void OnPopup(object sender, PopupEventArgs e) // use this event to set the size of the tool tip
    {
        e.ToolTipSize = new Size(200, 100);
    }

    private void OnDraw(object sender, DrawToolTipEventArgs e) // use this event to customise the tool tip
    {
        Graphics g = e.Graphics;

        LinearGradientBrush b = new LinearGradientBrush(e.Bounds,
            Color.GreenYellow, Color.MintCream, 45f);

        g.FillRectangle(b, e.Bounds);

        g.DrawRectangle(new Pen(Brushes.Red, 1), new Rectangle(e.Bounds.X, e.Bounds.Y,
            e.Bounds.Width - 1, e.Bounds.Height - 1));

        g.DrawString(e.ToolTipText, new Font(e.Font, FontStyle.Bold), Brushes.Silver,
            new PointF(e.Bounds.X + 6, e.Bounds.Y + 6)); // shadow layer
        g.DrawString(e.ToolTipText, new Font(e.Font, FontStyle.Bold), Brushes.Black,
            new PointF(e.Bounds.X + 5, e.Bounds.Y + 5)); // top layer

        b.Dispose();
    }
}

Any suggestion?

Thanking you in anticipation.

You could just draw an ellipse then add a piece to point to the target.

But why not use the default tooltip control.

It has a IsBalloon flag that when set to true looks like this:
