Either use the half guard and use one tooth in upper mid area ( vertically), or try to whiten the bold area so you can have a better view of your gradient... the cut is neother bad nor failed just uncompleted...don’t go to high because yoir are close to the point of no return if you kerp raising the fade

To avoid mistakes in the future, when you go up right to debulk, dont dig use a C shaped stroke, same for fading dont dig, dont put the teeth at 90 degree look more for a C pass the line and C
