Hello,
we opened your attachment but we can't find the powerpoint with .pptx extension.
all we see is with .xml extension. can you try just the powerpoint in 2010 version?

thanks a lot for the time.

cheers!

What is the color palette? just black and white? or maybe strong matte colors?

I''ve uploaded the file

I''m open to strong matte colors and a few b/w concepts.
