Backgrounds start with one or two rounds of thumbnail sketches where I already keep in mind possible animation options and try out different colour palettes. Then I will do one or two colour sketches where I start defining specific elements in the background and decide on the final composition. Then finally I will do lineart, colour, shading and rendering of the final background, always keeping values in mind so that the characters and the UI still pop.
In Skatfreunde there will be an option to craft different themed decks, but these cards are part of our take on the classic Skat deck that all players know and love, but adapting it to our aesthetic while making the characters a bit more inclusive.
