Squats look pretty decent, shove your knees out, knees won't slide forward that little bit. Keep working hard to do that. When you hit the bottom, if'n your tight and your knees are right, you'll have a better bounce and subsequent drive.
Deadlift: Lose the straps, if the weight is light enough that your walking around with it at the top, it probably shouldn't take more than a minute to do a set of 5. 20 seconds strikes me as a reasonable arbitrary number of seconds. Other than that, I don't see anything particularly wrong, except that you likely need more weight on the bar.
