Hm... I don't mind not being paid I love making comic covers as it's like the stage for the comic itself and what it entails without giving any words...
This is the cover I made for Soul Stasis and the Novel for it. I use some vivid colors and dark shading/shadow and some glow but with sharp lineart. I can also use any other colors but I prefer dark and dense for my personal series.

If you'd like some more reference on my artstyle here is my UnVale:
