I like the quality of your sample images. They look like screenshots from the anime. However, the quality of the images I made in the website's image generator doesn't appear like your sample images. How can I make my images look similar to the sample images?

If you have the chance, do you think you can do the other characters such as Houki, Ichika, and the heroines from Infinite Stratos?
