To clarify, I take points off when it's obvious from the image quality that waifu2x was used (a good waifu2x result will just look like an original). And I do the same if something looks cropped (a good image shouldn't look cropped...). So uploading cropped waifu2x images should be done with caution. Please try to choose ideal images and if one doesn't look very good after crop+waifu2x, don't upload it.
