Good job. Just one pointer comes to mind - you mentioned you focused on the rear sight and let the target and front sight go blury. You should actually be focusing on the front sight at all times. I have three decades of competitive shooting under my belt and a great deal of profesional training as well. If you can see nothing else, make sure you see that front sight. It's kind of unnatural, even counter-intuitive at first, but make yourself do it anyway. You will be glad you did.
