The cleans looked good to me..On the head position, fixate on a point straight in front of you, just look straight ahead.......I'm not sure what you mean about the hips, you make a movement to squat under the bar which is correct, and you pull yourself underneath, and remain in a good position to front squat. ......you look like you have a good, natural rebend of the knees on both cleans and clean pulls.......if you can be more specific on your concerns with the hips, it would help, but it looked okay.
The clean pulls were good too, they were explosive and snappy, and you finished the pull on them and reached full extension (on both vids).......NO don't slow the bar down with the quads....as you rebend, the bar will brush them, thats fine, so long as you don't knock the bar out forward and off it's upward flight (which u didn't)
