Those windows in the background took me about 3 days, and a trip to town to take over 100 reference images. It also required about 15 cups of various teas, a cherry square, and a possibly unhealthy amount of chocolate.
For reference, most pages can be completed within 3 days from thumbnails to coloured and textured page. The windows themselves took as long as the rest of the page. t
Of course, then Shamus looked at me a day after I'd completed the page and said "there's an awful lot of leaves on those bushes outside the windows." It's supposed to be early spring in Belydon right now.
