Amateurish.
It barely looks like a banana. It's shaped more like a boomerang than a banana. The way you shaded it doesn't go well with its crudely drawn limbs. You shouldn't rely so much on the shape tool either. It makes the image look jagged.
The image quality is also bad. This is because it is saved as a .jpg, rather than a .png. Next time you draw something, be sure to save it as a .png.
