I work as an artist mainly for Game development, creating scenery and other kinds of concept art, but also do all kind of illustration jobs, also have some experience on unity2D and as well on animation, regarding the hollow knight style, I am a big fan of the game, so decided to learn their art style while adding my own flavour of course, as shown on this small asset. (but I hope it does not feel like a cheap copy.)
Ahh I see, cool. I like the lighting, I think it would be good to hit 1) a colder, damper, darker transtional area, 2) a swampish/water transitional area, and lastly a 3) sun shining through type of area. Could be in any order, and depending on the vibe could be based on the dark cold feel to being freed to the outside world: 1) -> 2) -> this theme -> 3). Just an idea.
