*I use the exact same brushes for the eraser. However sometimes I use the airbrushing 'hard airbrush' one when I need it to go fast or erase bigger areas
I work solely with brushes which came pre-programmed in procreate
I do all the sketching with the HB pencil brush. I also use it as a texture for skin and soft shadows*
*For the texture and overall shading I use a mix of the inking brush 'thylacine', the drawing brush 'styx' and the callygraphy brush 'shale brush'
I then always alternate between all these brushes*
