Cave Story: Night Spirit Background

I decided since today is Halloween I thought to myself why not draw the night spirit from Cave story. I mean like they literally spill out Halloween because there cat ghosts. Yes, I know there are Skeletons from the Sand Zone, the Dragon Zombies and many others I didn't say yet. I choose this because deals with Blue. The only thing that was difficult of drawing this was shading using same color and mixing other color who are in the same family. Once again, I hope you like this and enjoy Halloween.
