At this stage, a type designer has to resist manipulation. It is tempting to actually start deriving the final forms at this stage. But that again will hamper the output. It is essential that a type designer works merely as a copy artist.
In the above image, you can notice:
(i) How the hand drawn letter, now vectorized, is placed on the pixel grid. The thrust keylines (in pink) are clearly defined.
(ii) How the pixel form is derived behind the vectorized form
(iii) How the pixel form behaves with just the support of grid
(iv) How the pixel form behaves without the support of grid or the vectorized form
(v) How the pipel form behaves in the acutal size
At this stage, as a type designer, you need to go back and see if the form is balanced. At this stage, one can vaguely touch upon aesthetics too. It is also important to see how it renders in actual size because at the end of the day user interacts with the actual size.
