Thinking about the mechanic...

The gesture of thinking during artful work is perfectly captured! May be the print could be a little bit brightened up, without clipping the highlights.

Thanks for you remark. It did not struck me, but it's obvious after you made the comment : I need to print it a bit lighter. I thought the scan (cheap-end 15 years old scan) was the cause, but the print isn't very much lighter...

powerful image !! very nice
