Always the bridesmaid, never the bride--or maybe in this case I should say, "Always the sidekick, never the star"?
Regardless, given the backseat nature of Luigi's life, it's easy enough to imagine that he may not be the most cheerful and positive chap. Is it possible, though, that his brother's annoying omnipresence has pushed him to contemplate suicide? I, for one, hope not, but New Zealand-based artist SUIKA seems to think otherwise.
Granted, SUIKA also believes Mario to be teetering on the edge (see this similar piece from earlier this year), so maybe I should take his thoughts on the matter with the proverbial grain of salt.
By the way, the Luigi painting above is 400 mm by 550 mm in size and was made (with acrylics) using a 17-mm-by-17-mm and 5-mm-by-5-mm hand-drawn grid.
