Yep that's right, this art piece was made with just five colours.
It was a contest on a site I'm member of and the contest still is to make a drawing (digital) with the colour palettes they made.
You aren't allowed to use any other colours than those, but you are allowed to mix 'em up. Also transparency is allowed.

I don't think I'll enter it, since my bottle of inspiration for big drawings is empty.

Any ways on to the picture:



For the ones who want to try it as well these are the palettes:

Hmm, I like it! And the colors in the palette you chose are much better than the other option; less harsh and saturated.

I do think you could've tried a little harder with the shading on her forehead though, and actually brought the shadow up into her fringe. Also, the bow looks slapped on due to the lack of an outline.
