For my own tastes, this is one of those maps where the elements and their arrangement can strongly suggest the scale all on their own (and it can lend a note of authenticity, depending on whether the map is meant to feel "in-setting" or not). I don't think the scale bar harms anything (I wouldn't want to earn the ire of Del, anyway, since it obviously means a lot to him) but I think this map could get on just fine without one. Heck, I don't think I've done a fantasy map with a literal [physical] scale in years, now (I tend to use chronographs when I provide a scale at all).
I think the buildings went and got awesome. I liked the water pretty much equally both ways.I messed around with the water a bit -- though I'm not sure I like it better than the first one. I rather liked that 'painterly' quality -- and I played around a bit more with the buildings.
