I will draw all 6 girls in the form of the Winx heroines (I will not draw Sci-Twi). To be honest, I associate Stella more with Sunset, because both of them are associated with the sun (and this is a very important fact), but I will not go away from the fact that you need to compare the main characters, so Sunset will be in the form of Bloom (by the way, they are very similar in color to the hair))
