Find your Sensei's Sensei. He is probably less likely to ignore bad habbits because he thinks your improving. Then do every technique in front of him. Hold every stance for three minutes, do every form for him, and every drill. Then explain every concept you have been taught. And finally do every form of free style you know with someone who is not a student of your sensei.
Then, if he says you're doing someting wrong, or it needs improvement. Well it needs improvment. And then drill it 10,000 times. Why? Do your kata 1,000 times and you begin to see the enemy, do your kata 10,000 times and the people around you begin to see your enemy.
Then after 5 years of hard training and doing what was wrong 10,000 times the right way, go back and do it again. and same thing, anything that is wrong do it 10,000 times.
