Certainly looks like you're on the right track. Nice shooting using a 4x optic. More time pulling the trigger to get used to your rifle will help a great deal.
If you are interested in learning to shoot from different positions, other than from a benchrest, see if you can find a CMP group in your area. I have found those shooters to be very willing to help a new shooter out learning shooting from different positions. Marksmanship will then carry over to other shooting types.
