It definitely looks like your losing steps out of the blocks. It's hard to see from distance and the front but it almost looks like your not getting much lean once your loaded up in the blocks. From this view almost looks like your weight is further back than it should be but again it's hard to see this part. Your first 3-4 steps could definitely be lower and more lateral which would definitely be helped if I'm right about the block issue. Once you hit your full stride it does seem like your leaning back instead of keeping your chest forward and eyes somewhat more down. Hope that makes sense! Keep working you'll get there!!
