Danny:
This is exactly the method I use to teach height judgement.
Next time you fly with your instructor have him / her verbally track the height above the runway starting at fifty feet.....50...40...30...20....start flare....15...10...5...hold off......4. 3. 2 .1 contact surface.
The student then learns what the picture should look like.
During the latter part of the final approach you use the flare point as your aim point.
Go back to the start of this thread and read my post.
After you have flared to the level attitude if you look to close in the runway / ground will blur....if you look to far in the distance the angle becomes too flat for proper height judgment.
After you have flared to the level attitude your center of vision should be about five hundred feet down the runway ahead of you.
