I came across a tutorial on how to colour black and white drawings. I wanted to try it as I had never tried rendering a drawing like this and I like the look it creates as it reminds me of book illustrations.
The link to the tutorial is here: https://www.youtube.com/watch?v=zurMZ97uLKM
I really like how this image has turned out and hope to use this technique in the future.
Clean up lines
Grey scale (longest part, took around 7-8 hours for me)
Soft light colour layer with out grey scale underneath
