Here's the guide (not in order of importance) -

1. Godzilla and literally any other kaiju movies and tokusatsu genres

2. Tetsuo Hara , I love his art especially for my favorite fist of the north star

3. Frank Frazetta, his art is awesome , The men are badass strong heroes. The women are sexy damsels in distress. The villains are superhuman. Much of his art represents a scene of action. When he paints a battle you can feel the fury of that battle play out in your mind.

4. Boris Vallejo , I like the style of sharpness and its very vibrant.

5. Joe Jusko, similar to Frank and Boris but there's a badass unqieness to his work , I think 

6. Sheikh Mohammed Sultan, a Bengali decolonial artist who worked in painting and drawing. His fame rests on his striking depictions of exaggeratedly muscular Bangladeshi peasants engaged in the activities of their everyday lives. I love his philosophy , Sultan And His Philosophy Of Art | Print Version (daily-sun.com)

7. Pulp art, since high school it helped me to improve my art skills 

8. Newgrounds, since 6th grade I played alot of flash games and strangley it influence the way I draw

9. Paleo art, there are so many paleoartist , personal favorites are Ricardo Delgado and William Stout and I wanted to be paleoartist when I very young
