A few months ago I designed a character. She is a waitress. I enjoyed the way my pencil sketch looked more than the digital work, and now I have had more practice digitally painting I felt I could do a better colour headshot.
Last time I painted with all brushes and layers on 100% opacity; since then I have learnt a lot about changing opacity layers, and that the blending brush is not the only way to blend and shade.
I learnt to do this recently and it was difficult to learn as someone who can spend hours blending colours as if they were paints. I definitely treat my digital painting like acrylic paints for the longest time (something I would always use in traditional media) with the bold unforgiving colours and difficult blending for a vibrant result. I am only now learning to sometimes treat the work like watercolours too.
For this I actually painted on top of the pencil lines in Photoshop, with low opacity layers being built up, letting the original sketch show through. I am learning that not everything needs to be smooth to have the right effect, and that often that can subtract style from a piece.
This version is more muted, and more rough, which I like. It also meant I could follow my original line art and not start from scratch.
