Good luck on your cleaning. It's one of the things I hate most.

And as I said before, "not drawing exact details" doesn't mandatory mean drawing simply; and anyway, drawing simply can be reaaaaaaally hard. In fact, it's often harder to get a "finished" and expressive yet simple drawing.

You might also want to try some effects that are nice, as such:

• prepare the composition of your illustration (rough)
• sketch the whole illustration
• over-detail/paint just some "highlights" or "focus points" on your illustration.

To get the idea, apply what you've done to the hair on the bottom left of the drawing above, but to a whole illustration with a background and such.

Given the style you have, I feel this could look great.
