Super Mario Bros. NES Realistic Cover [WIP]

A project of video games covers adaptations :

In my playful evolution, there were the video games. And many really impressed me !
Super Mario Bros. is one of those ; it is my very first video game, and at six years old... It thrill !

The aim of this project is to adapt, in realistic style and with my vision, these covers of retro gaming titles ; those of my childhood.
So, the first of them is the game Super Mario Bros. (NES)

I tried to bring out emotions that could not be shown on the original seven pixel high head of Mario. So, I decided to illustrate an humorous representation that could contrast with the seriousness and rigidity that a realistic style can bring.
The first idea was to represent a Mario tired of running and jumping from castle to castle in search of Princess Peach (cf. Princess Toadstool). It can also express his long career in video games.
But I also wanted him to wear an impassive face for his ease to brave the level design when the player is working his skill.
