mitch, good work. It's obviously much better than the empty lots and random stuff that is there now. However, the only thing that's off-putting (only IMO) is the complete randomness of everything. I like the streets where you put rows of townhouses or rowhouses facing the streets, or the row of lower-rise commercial, but then you have other areas where the buildings seem to turn in on themselves and cater to the interior courtyards or pedestrial mall looking areas.
My ultimate goal for this area would be for it to be constructed like old European cities. All streets would be lined with store fronts (with residential on top) or just row houses. It would completely encircle all of the empty blocks, with the same street-front minimal setback 3-5 story buildings. Then, the interiors would have courtyards. Like this from Rome:
