Well, those shots are all definitely to the left. Have you tested yourself for eye dominance and determined which is your dominant eye? Many folks think just because they're right-handed that their dominant eye is the right one, but this is not true for all shooters. About 30% are actually cross-eye dominant. For one reason or another their brains have swapped their dominant eye over to the stronger of the two eyes - not uncommon for people since we have binocular vision for depth perception.
By cupping your hands in this manner, you can keep both eyes open and use them to see a distant object through the small opening between the fingers. Then retract the hands back toward your face, all while keeping the distant object in clear view. Your hands should align with the dominant eye and move rearward toward that eye. That is your dominant eye.
Another method is to look at the object through the hands (as shown above) with both eyes open. Next alternately close one eye at a time. The eye that allows the object to be seen without moving the hands is the dominant one.
Also check to ensure that your rear sight is close to the centerline of your pistol. If its not then it may be off causing the shots to be left even thought the sight picture is proper.

There's a lot to read and try here so I'll let you look at some of this and then I'll comment more if you have some questions.
Here is my version of the target analysis wheel.
Hope this helps.
