I took part in a Detective art swap on Ten Paces and draw and got a lovely sketch from Levi Hastings to work with.
(Everybody of the participants has to do a sketch which get swapped and one has to do a final illustration to the sketch one received.)
I stayed pretty close to the sketch, you can see it and the other swap participants here.
And this was my sketch, which Levi had to do a final illustration to:
Coincidentally I had a similiar idea like Levi. ;)
