Acrylics and Inktense pencils

I love to try out new things, even running the danger of damaging artwork I'd already done (at least, I got a scan of it!).

This is the scan of a painting I'd done with acrylics. I was quite satisfied with the composition and the choice of colors, but when I looked at it I had the feeling that it needed some shading. 

I remembered that I had gone over my marker paintings with inktense pencils and quite liked the effect. So why not try using inktense pencils over acrylics? I did a quick search on YouTube, and could not find anybody who'd tried it. So I had to experiment.

And this is the result:

Well, it seemed to work. It is definitely not as flat as the painting above. And I definitely want to keep on with the combination of acrylics and inktense pencils.
