>Software 
Sai, Photoshop. 
>Hardware 
Shitty laptop. 
>Style 
I try to draw very high quality anime with elements of realism, but I hate having to stick to one style and I experiment with all kinds of styles until I hopefully find the style I love best. 
>Tool (i.e. Pen and Paper, Stencils...) 
Paper + mechanical pencil, keyboard + mouse. I sketch out different ideas on paper, but I scan them and then trace the sketches on Sai with the lineart tool, and colour/shade it in Photoshop.
