Your squat is very good. It's not "too" horizontal at all. In fact, this is a pretty good example of correct technique, once you realize that the squat is also a back exercise. The only change I would make is to point your toes out a little more.
But your back is way too horizontal in the deadlift. This is essentially a stiff-legged deadlift. You need to get set in the same position you're using now, and the squeeze your chest up as high as you can. This will drop your back angle to the correct position before you pull.
