Form looks good, grip nice too and also follow through. Your groups will tighten as you go. I tried what is called instinctive and wasn't to bad. Later went to gap shooting 3 under, middle finger in the corner and found I was much more accurate/consistent so I switched over. I don't spend enough time shooting anymore to keep the accuracy I need shooting instinctive. Either way there's nothing wrong with it...You look like you really enjoy shooting. Keep at it and have fun. Beautiful area to practice...
