what makes these gfx good is the personality behind them.
I believe my “gfx” attempt lacks personality, I refuse to use AI but i dont want to commission someone, I no longer have a drawing tablet and drawing with a mouse is extremely difficult, so i tried to do this in blender, so its technically a 3d model i tried adding imperfections to.
As for criticism, I do think that the colors can be pushed to be a smidge brighter (maybe putting the Color Mode to Filmic if you haven’t already) – and from the references you’ve provided – some color in the outlines could be implemented as well.
