iPad Pro 12.9" (2019) /w Apple Pencil Procreate for sketching and drafting. Clip Studio Paint for the finished product.
Procreate is an enjoyable scratch pad with it's simple interface and helpful liquefy tools to help push my lines around when I draw things wrong.
Clip Studio Paint offers the most efficient line art and colouring work flow by using vectors for line art which greatly speed up the inking process. The flexibility is endless. Raster colouring is achieved easily in conjunction with Vector line art as they always fill to the centre of the line, not the outside. Vector lines can be thinned or thickened and the whole colour work survives.
