Hi Karla
I have an idea to try working on the Intonaco in different ways like for instance applying background colors first and than drawing in a free modern way on top, that way I hope to achieve different result from the traitional clean look of the Fresco. I think that you try to achive also some kind of different and more personal expression. The old masters worked according to conceptions of their time. Do not hasitate to try ALL kinds of ways, including "wrong" ways to find your way. The more mistakes you do the more you learn about this beautifull technique and you might even find along this experiments some new original solutions. Hello to you from Ajanta. I have just been there.
Good luck
Yoram
