E-rated? I see nipple outlines, I do recommend putting it in "M" or T due to clearly being sexual in nature ( I make smut as well )... The resolution of these images are admittedly a little too high for something so simple... I am fully aware there is some texture, but I am questioning the " 3300 x 4200 " for simple coloring and shading... You ain't gaining anything in a high resolution sadly. People look out, not in... This is a true lesson from from a digital painter, may work lineless, but don't put detail in areas that AREN'T VIEWED, so drop an edge or get a focus on them. If it looks good far away or medium views, then I would say it is okay to be high resolution. I am still puzzled about the lack of a good use of high resolution. Most people view on mobile devices, or not in 4K.
