welcome!
looks like you are starting without your shoulder blades over the bar. get yourself over the bar more so the blades are directly over top of the bar. it's not causing a problem now because the weight is too light for you.
have you done Starting Strength linear progression? Reading between the lines of your post, I'd guess you have not. Don't start with a 5x5. If you are indeed a novice, you will get much stronger much faster with linear progression.
oh and lose the gloves. replace with chalk!
