Interdimensional Beings

Wonderfull ! What a work ! And I love the idea of aliens ! haha ! Your colors and patterns are so great ! Could you tell me on what kind of paper you are drawing please (I'm not use to that sort of draws and I really love it !What is the name for this ? Do you start the draw by a black pencil first ? What color pens are you using ?) Is there a website I can read to know more ? Thanks by advance for your answers !
