I got an idea to make vector-based superheroes and villains fan arts in summer 2014. I inspired from superheroes movies and posters for references. More links; behance, facebook, and twitter. This is the fan arts of superheroes part (1) and will be continued.
1. Captain America
I inspired Captain America (Steve Rogers) from his original poster and drawing time is about 5 hours. First illustration for superheroes and background mark is his shield.
2. Black Widow
Black Widow (Natasha) is also inspired from original poster and needed 6 hours to complete. First women superheroes illustration and background mark is S.H.I.E.L.D logo.
Wolverine (Logan) is my most favorite hero from x-men and marvel. This artwork is inspired from side posters and illustration time is 5 hours. Background mark is x-men logo.
I inspired Hulk (Bruce Banner) from side posters and illustration time is 4 hours. Background is simple circle.
