One thing about Dunedin is that it gets cold in the winter -- whether or not to include snow textures is a big issue at the moment. I've always steered away from multi-season textures with photo-scenery, for two reasons -- first, the photos which the scenery is built from is nearly always high summer, but the main reason is the sheer size of the scenery files. Adding a season doubles the size of the download, and my scenery tends towards big downloads ever for a single summer season. For some reason adding snow makes a particular large seasonal file, which is about 30% larger than a non-snow season.
However, as I said, Dunedin gets cold in the winter, so I have to decide if this is first and foremost a photo-scenery, or a full-featured airport scenery, in which case it should have a winter version at least. (Adding all five FS seasons plus night is really out of the question here, as it would be heading towards a 10BG download.)
There are various options, such as offering summer/winter as a separate download, so that a 'normal' download might be 1.4GB or thereabouts, and a 2-season version might be closer to 2.5GB.
Anyway, still plenty of work to do on the scenery, but I've been having fun blatting around a snow-covered Peninsula. (The other side of the harbour is only partly painted with snow at the moment.)
