not that guy, but - no
People severely misunderstand what a concept artist is - Ruan Jia is an illustrator, he is a very poor designer, many of his designs dont seem designed or thought out, or intruiguing from a narrative/ world building point of view, which is what most concept artists actually help with working on a game or film, apart from the people like him who do sexy splash art for loading screens.
A lot of these paintings hes making are completely devoid of narrative and concept, and are very rendered visual spectacles, that dont have a lifespan beyond the appreciation for the rendering of the vibration of the colors.
He is very good at painting, and navigating contrast, but he uses his skills very poorly from a narrative and poetic point of view.
He is basically a person with very articulate language, full of colourful words - who knows grammar very well, but who couldnt write a captivating heartfelt poem if his life depended on it.
