Hello, i’m trying to build a series of painting, model and animation.

Can i get some suggestions on how to go?

I know the objects and the compositions to go about it…
the hardest part is to make harmonious color that does not stand out too much, and direct the ye across the paintings…

I like the style and amount of detail In the old traditional paintings they would use the color Red in key areas. I don’t know if I would use red but a special color that is just different enough to pop out may work.

Some Influences from Ponyo in second pic, huh?
