Improvements needed urgently

This app is okay. But, the render is unequal and it is extremely difficult, if not impossible, to tweak the sliders to keep the overall feel and texture throughout the page and books. We can see a significant difference from one image to another. The PDF generator is faulty. There is an overlap of processed images in the top right corner. Some outlines are also faulty... The black is not solide everywhere. We can see the image underneath. The manga style is funny... Most of the time only puzzling shades of grey. Very few stickers may be used in the manga style, for they are colour. The stickers are not framed by black outlines. They very easily cover other images. Not very user-friendly.
