confession time: these were my styles from 9 and 5 years ago.
i went through phases, photo-realism to painterly-anime to simplistic; whether born out of necessity or due to change in taste. each style has its own merits and not to be judged.
i also tend to leave a style if i start to feel too comfortable, expand the skill-set as much as possible. because Any road followed precisely to its end leads precisely nowhere.
