Narrative:

A G5 was on left downwind for dal. I tightened up his downwind for a short approach to get in front of base traffic from the northeast; but it was too tight for the departure off dal. Recommendation; don't be so tight on the downwind at dal; or switch aircraft to dal tower earlier so they can provide visual separation.
