Roman or Arabic?

I printed out copies of the clock drawing without the numbers in the panels. That way I could experiment to see what looks best before I permanently add them to the finished rendering. 

For the finished clock sculpture the plan is to cut and carve the numbers out of brass. Then behind them I’d like to try Kitikata rice paper. The end result should have a feel similar to the panels on “Th3” (picture below)

I tried a bunch of styles, but these two worked the best. I included images with and without hands. The hands are actually from the drawing of “The Grasmere Commission”, so the style of them might change for the final piece.
