Your draw length now is most likely ok........your use of it isn't IMO.

You need to transpose everything forward a little bit......get your arm more straight and bring the anchor forward to stay "behind the shot".
The push pull thing IMO doesn't work on compounds, its to hard to repeat the pressures involved and you will wind up with variances in hand pressure and torquing forces on the grip.

Treat your bow arm like a 2X4 with your shoulder down and in a locked bone on bone position with good relaxed hand placement. and FORGET IT. From there on out you simply pull with your back muscles. Both hand should be relaxed and PULL only.

I could get into a bunch of stuff from those first pics but first and foremost scrap that anchor and bow arm style.

I included a pic of my "Tournament style" form. I have actually since shortened my draw length myself 1/2 " on a longer ATA style bow to maintain my consistent set of reference points and to be able to stay behind the shot even better on uphill , downhill shots. I will actually mess with loop length in 1/8" increments to get things just right.
