First, I discovered the sculpt tool in Blender, and it was much easier than I thought because I already knew how to sculpt in ZBrush. In Blender, I used basic tools and watched a lot of tutorials.
The secret of my topology was the Automatic button. My goal was to finish a cool 3D sculpt as fast as possible. The best part was texturing. UVs were also automatic (yes, I know, my UV maps are really horrible to see).
I used Substance 3D Painter and imported Blender’s camera into the software to paint textures from the camera view. To achieve this painterly effect, I just painted directly with a brush. Painting the impact of light on the character was the most challenging step during the process for me because I really wanted to paint light exactly like in a 2D illustration.
