You can try this: starting from the drawed image: redo all up to have all dots drawed. select all. copy paste as new image undo up to pristine state before drawing dots but after the enhancements. select all (you will not be able anymore to redo) copy in the new image: duplicate the layer (as this you have a backup of the dots) hide the duplicate add a new layer import the pristine state into it -> paste duplicate it and hide the duplicate (you will need later) raise the visible drawed layer to top. set mode in the drawed layer to divide if the dots are not white or black. else to grain extract. flat visible layers. (drawed and pristine) color to alpha (white if there was divide or grey if grain extract) if grain extract select by color transparent, invert selection and fill the dots with original color set the duplicate of pristine layer visible and down it.
