Keep at it! After the scale feels fairly intuitive (meaning you don't keep wanting to leave the bottom holes open as you play top-hand notes), start just noodling with the chanter. Try to play a couple of tunes you know by ear. Frere Jacques and Jingle Bells are great examples.

These tunes don't really build piping technique (you'll get plenty of scale exercises for that), but they do build familiarity with the instrument and where the notes are. This will make learning tunes easier. And anything that makes it easier is a good thing.
