And, here's a brief step by step of the recent Toph, including the very early rough thumbnails that I do to mostly plan the picture and figure out the composition, and as you can see it's usually just a very rough approach and many scribbles and shapes but it helps a lot!
Now then since this drawing is mostly done with flat colors, there's not really many special types of layers and all, it's mostly normal layers and just slapped a quick overlay in the end to make colors warmer.
Hope you like it ! ♥
