Here is my drawing. I really thought about it in a way I could use the hatching techniques. I really like the result.
First I stoped without filling the sky in the background, but I felt like something was missing. I struggled a bit though because I wanted a different texture than the torii gate. I was afraid the contours and the sky could "melt/mix". And also I was afraid to "fail" hatching the sky (cause it was a huge surface to fill) and ended up with a very dirty/messy result.
Anyway, at one point, I though about the dots. And here we are! I would have liked using a thiner pen for the doting, but the surface was very big so I opted for a thick one.
What do you think? If you have any advice for filling large background, please feel free! :)
