Starting position: your knees are extended passed your arms they should be even with the arms (only in the clean your knees extend passed your arms), you compensate with this by shooting your hips in the pull. (shooting hips = hips rising quicker than shoulders)
2nd pull aka "scoop": because your hips shoot first, the bar hangs down, you compensate by scooping low and forward to throw momentum into it which guides the bar up and out, and you extend too much on your toes.
Landing: because you scoop forward and extend too much on your toes, you have to compensate by catching and landing on your forefoot. (scoop low and forward + landing on forefoot = miss catch).
cues would be:
1) on the setup have your knees even with your elbows
2) in the pull, keep your back at a solid angle rather than hips move faster than shoulders, using only legs to extend in the pull
3) in the jump, jump "flat footed" and stomp on the landing, the stomping will make you land on your whole foot and with a stronger base when you go into the ohs, rather than land on your forefoot. If you can't jump "flat footed", skip backwards.
