Need some practice

After shuffling through my recent picture attempts and playing around with a new lens on my camera, I am about to throw my hands up in the air and scream for help. Having a real problem with no controlling the focus. Only part of my photo is focusing. For example, look at this. Chase is focused but not Kelsey.

Or look at this one, same thing.

 Next weekend an important wedding is going to happen and I need to practice. What better way then the photo a day. AGAIN. Here is the August list if you want to play along. Good luck as we work to improve our photos!
