Character consistency. Bellatrix is a very complex character, and in a good fanfic, she should still retain her wild and somewhat unhinged nature, while Harry should also be true to his character. For example, his sense of justice should be there.
The magical elements should be well - written. Since it's set in the Harry Potter universe, the spells, the magic items, and the different magical locations should be described vividly. If it's about Harry and Bellatrix, perhaps there are some unique magical interactions between them due to their opposing natures in the magical spectrum.

Character development is key. You want to see how Harry and Cedric are portrayed differently from the original series yet still stay true to their core personalities. Also, the lemon aspect should be in harmony with the overall story, not just thrown in randomly.
