DIVA Challenge # 229 Positive and Negative

This week we had an interesting challenge by guest blogger Sandy Hunter (CZT):
We should shift our focus to the negative space - the white part of the tile. When I started to draw I thought that it might be interesting to intensify this effect with the other extreme and to add some black space.
So I managed it at sunday evening to complete this challenge after a very busy week and weekend...

Thank you Sandy for this interesting challenge and this experience!
