The GUI looks real good
The areas however could use some improving:
ProjectsP3 in particular there are shadows running in at least 2 different directions. I'd suggest that you cut those associated with the thieves’ guild maybe even lighten the walls that are shadowed as well. Shadowing can be tricky and a huge pain.
You have grass borders that end abruptly or just look flat, meaning that there is no illusion of differentiating elevations between the pavement/cobblestones and the grass. Suggestion, since the grass in real life is usually higher that the sidewalks I highlight the edge of the grass slightly (next to any pavement) and darken the stonework a bit near the edge of the grass.
I also think that some of you compositions are real good.
It is good to see more people making areas. keep on keeping on

Sorry, if you are like me, I hate to hear criticism too when it first comes out but I learn from it, we all start somewhere.
as far as having a large mod WTP is no small mod either so I know what you are talking about. However you should not rush something just to get it out there.
The ares do not need to be better than biowares (a tricky thing to do, they are great artists).
if you ever need any tips, suggestions, or have concerns reguarding graphics. Ill be glad to offer my help and others might help too there is a lot of experence in CG here.
