This is the cover I made last year for my friend Donuts3132 's book Smashing Live. All characters are 100% drawn by me. (But not owned, obviously.)

This style has the drawing being completely digital, no photos of paper. This makes it look smoother. Personally, I don't think this cover is as great as it could be, I need to give her an update (my art skills have improved a lot over the last year). I can do chibi (like the chapter cover for the rules) or semi-realistic like this cover.
