Not Caslin #5

I thought this was Joe Caslin's fifth portrait but ... apppears not when I check his website:

Drawing No. 5
22nd April, Under George IV Bridge, Cowgate, Edinburgh.

SO ... this is an extra on Holyrood Road that isn't referenced on his website. Nice detail and use of hatched shading (or whatever the arty term for this style is called) in this close up me thinks!
