Here's a picture I particularly liked working on : it depicts Mario on his natal Brooklyn, ideally before he landed in the Mushroom Kingdom. I'm aware of the fact I didn't use the old colour scheme on a scene that particularly asks for it, but after a couple trials at different states in the colouring process I thoroughly hated how it looked like, so I just gave up. Anyway the sepia look make the colours fade a bit so it's not too much of an issue. I used a few references to get the Brooklyn-like background acceptable, but most of the infrastructures here are fictive.
This thingie is completely drawn in Adobe Illustrator, then brought into Adobe Photoshop for the colouring job.
P.S.: I know there are a lot of contentiousness surrounding Mario's origins, as to know if he's born in Brooklyn or in The Mushroom Kingdom. I ask you to keep that topic at a minimum, please. I don't wanna start a debate. Just comment on the pic, and everyone will be happy. Thanks.
I think he was born in Mushroom Kingdom(kind of revealed in Yoshi's island),was attacked along with his bro by Bowser,after awhile moved to the "Real World" of Brooklyn(It could be in the same Mushroom Universe or a different dimension of Earth),then returned in a mishap plumbing service and ruined Bowser's plans.
Something like that at least...
