Painting Blood Bowl Imps Using Only Washes

One technique I haven't used much when painting is painting miniatures using only washes.  I tried the technique on some Imps from Impact Miniatures that I plan on using in a custom variant of Blitz Bowl.

I first primed the Imps white.  I then shaded their skin with a yellow wash, then washed the skin with a green wash once that was dry.  The red and purple areas were first washed, then hit with a coat of Vallejo paint when the wash colors weren't saturated enough for my tastes.  I finally hit the silver parts with a metallic Sharpie marker.  So... it ended up that I did not only painting them with washes, but with a mixture of techniques instead.

These are first miniatures that I haven't used a dipping media on in a long time.  They turned out fairly bright, and for the very minimal time I spent painting them, I'm happy with the results....
