5 Detail and sharp edges
Now, you can really get into those details and polish your colour piece. Add in your darkest darks now so they won’t become smudged by lighter colours. This is also the time to add in markings such as spots and stripes or anything that has a hard edge. Fur and scales can also be defined here, but keep it sparse: too much rendering can make forms look flat.
Things like pupils and deep cracks can be drawn in using a finetipped pen, like a Micron. You can also add in a bit of background indication to help pop your final colour job. It’s important to hold off on markings until the end. Things like stripes are best saved for last – they can smudge when drawn over.
