For this, I first sketched the style that was in my mind which is similar to this image/style, which I would classify as a more realistic take on anime style.
My second choice was a kind of chibi-style? which is similar to anime but in a much smaller scale and cuter. However, I wanted it to look creepy and so different styles were mixed for experimentation purposes.
I also thought about doing something that is Tim Burton inspired so I also search for that style.
