you need to erase the screentone patterns first before you do any colouring, instead you've kept the screentones (they are very apparent, just look at their faces, nipples and genitalia)
It just looks like they have freckles / little dots on otherwise smooth skin.
You should also be linking the source of the original translation and give credit to the actual translators who did the backbone of the work. In this case, credit should be given to Zero Translations for being the originals. https://e-hentai.org/g/1200367/c57b9552eb/
