Finally finished this job. I did it for about a week (if not two). Here are three of my OС (two of them are the main ones) - Dicaprio Aries Kat (cat with red hair) and Bakhtairus Alpein Abust Hunt (gray cat). Color rendering, fortunately, did not suffer much (it could be worse). The lighting went bad (my laptop had very bright light from the window and gloomy shadows near the main OС) and ,seems to be, nothing else has changed.
