For me when I making Sang Kong, due of color blindness the most tedious part for me are coloring or to be exact picking color, I must use ref and eyedrop tool to "steal" some colors.
second part, probably more personal problem when my family see me drawing comic, when I stop and rest they ask why I don't draw and act supportive, when I draw they talk to my back (literally) most of them mockery, when I talk back they use words like "it means we concerns about you". I choose not to listen to them anymore except if it was important, but still.. it's annoying.
Sorry about my English, it's not my native language
