Get up close to your target and THINK about your anchor, and if possible, use a double anchor. I slide my thumb base knuckle along side my face.....my middle finger reaches the corner of my mouth 1st, then as I continue to draw, my thumb base knuckle drops in behind my jaw under my ear.
Think about your anchor, and release. No aiming. It will take some time and repetition for you to burn that in. After a week or so try and aim at something at a short distance and see if you are grooved in....if not, go back to the target up close and focus again only on your release for another week.
That's what I would do if it were me.
