Brazilian artist, Marcio Hum, has been making wonderful illustrations of some of his favorite characters for years. Marvel Comics superheroes are some of his most common subjects, specifically the X-Men. His style typically looks like the X-Babies versions of the characters, or as he calls them the X-Mini. One of his best and most complete series involves showing the X-Men comic characters side by side with their movie counterparts.
Below I have compiled all of the illustrations from this particular series, but be sure to check out his sites for more of his amazing work.
