Thanks all of ya!
But don't forget that the drawing is the right half of what you see, and the left side is Photoshop-mirrored.
The pencil is a techical pencill (.3mm, no sharpening needed), mostly an "HB", and a bit of "4H" for general tinting on satin grain watercolour paper. As for the time...some 150-200 hours, I can't say exactly...when you do what you love doing, time is unimportant, even non-existing...
Like I always say (one of Saturn's big lessons): "If you don't work against time, time often works for you.
As for Medieval atmosphere: yes, end of Gothic, beginning of Renaissance is what I like most. I've even tried with a silverpoint like used in those days, but I prefer the graphite pencil of today.
One of my dreams is do something like this in Photoshop. But then I take a sheet of paper to make a quick sketch, and...there we go again... Yet it must be possible in Photoshop.
Thanks again!
