Felix the cat, backgrounds study

John K posted some covers on his blog, I used one of them to make a background study.

I want to learn how to make drawings like this. Where backgrounds and characters are one whole. With this study im trying to understand how the artist is planning this, so I could apply it to my own drawings.
Here I made a study, it's quite hard because you have to manage allot of things. I did it quite fast and think I could have done a better job if I take some more time for it. I will do that next time, I think I can learn really allot of these study's.

Made one with the focus on the characters. I think i could have got the lines better.
