Wing tips in a Glider Elevator

[gmoreno.id (Gmoreno)]

Hi all!
I was wondering how I could draw the elevator wing tips from this glider. As you can see in the attached picture, the wingtips goes down only in the tips… I’m driving crazy with this.

Many thanks in advance

This is how I handle them.

Gave it some more thought. You could handle it this way with sweep 2 rails.
