Maria it looks fantastic. Its not always easy to explain, even if you didnt need translation.  And sometimes we didnt know what happened LOL ! 

I completely forgot to tell what i did with mine.  I made a selection point to point in PSP9.  Inverted the selection and used a glass filter from PSP and inverted back and used cutout in  -3 white and in +3 black to create the edges. Then I made with white some lines to indicate cracks. Thats about it.

Mario, it is a really excellent abstract you have created. Such fun. :)
