未 not yet

I'm not yet the perfect ME.

未 is basically 末, but with a SHORTER upper stroke. . HOW TO TELL THEM APART;

未-tip - SHORT UPPER BRANCH on the tree

末 - not yet - LONG UPPER BRANCH on the tree

The MADA tree, the extra branch has not yet fully grown, that's why it is shorter than the middle one.

The SUE tree, however, the extra branch has grown ALL THE WAY TO THE TIP, which is why it's LONGER than the middle one.
