These are the brushes I use in sketchbook pro. None of them are really 'custom' in any sense that I built a special texture, the set is mainly the brushes I use in SBP. The brushes I use the most are at the top in relation to how I've arranged them in my brush tray below. The top two round brushes are used over 96% of the time. The rest might be used for detailing or blending towards the end.
