be very wary, a sketch looks very different when made into pixel art, I suggest you make sure it animates well in the sketch AND in the pixel art before you go into the deeper shading.
it doesn't matter if its important you, if you use it too early the animation process will be a massive pain in the ass and one thing you want more than good shading is a good overall sprite. (a broken wheel on a good car doesn't make the wheel look good, it makes the car look bad)
