My first thought upon seeing the hair was... "pumpkin person"? Then, when I looked at the shirt and the face, I thought, "Chara? From Undertale? As a pumpkin?" Haha! I love this work! It's really cute! I think the shading is done really well (noticing this because flat/cel shading is something I currently struggle with). But yeah, it looks very clean and professional. Well done!
