Understood. I did not see a scale yet, but I expect it's probably to small as is to really be a "perfect" VTT map. RPMiller, Dorpond, or Torstan would be able to share more, but I think the suggestion is 5 foot =50 px at a minimum, with 100, 150 or even 200 px per 5 foot being the best.
In any event, the map is a great piece of art no matter how you look at it and even if it can't be used very well for VTT, it makes a great player handout of a generic city. hmmm you might just have to get my vote for this months challenge again. argh!!!! there are SOOOO many awesome maps. It will be really hard to choose my pick for this month...
